#pragma interrupt/vect and the __interrupt and __interrupt_brk keywords of the CA78K0 are converted into #pragma interrupt/interrupt_brk of the CC-RL.
The format of an interrupt function of the CA78K0 is as follows.
|
<Normal model>
#pragma interrupt(vect) interrupt-request-name function-name function-name [Stack-change-specification] [{Stack-usage-specification | No-change-specification | Register-bank-specification}]
<Static model>
#pragma interrupt(vect) interrupt-request-name function-name function-name [{Shared-area-save/restore-specification | Save/restore-target}] [{Stack-usage-specification | No-change-specification | Register-bank-specification}]
|
or
|
__interrupt void func() { processing }
__interrupt_brk void func() { processing }
|
The format of an interrupt function of the CC-RL is as follows.
|
#pragma interrupt [(] function-name [([vect=address][,bank=register-bank][,enable={true|false}])][)]
function-declaration
#pragma interrupt_brk [(] function-name [([bank=register-bank][,enable={true|false}])][)]
function-declaration
|
- | When the interrupt request name exists, #include "iodefine.h" is output. A message is output because the interrupt request name may not be appropriate due to the device being changed. |
- | __interrupt is converted into #pragma interrupt and __interrupt_brk is converted into #pragma interrupt_brk. |
- | When the interrupt request name is BRK_I, it is converted into #pragma interrupt_brk. |
- | "interrupt-request-name" is converted into "vect=address" as a macro that indicates the address. The macro value is defined by iodefine.h. |
- | "Register-bank-specification" is converted into "bank=register-bank". |
- | Since "Stack-change-specification", "Stack-usage-specification", "No-change-specification", "Shared-area-save/restore-specification", and "Save/restore-target" do not exist in the CC-RL, the CcnvCA78K0 outputs a message and deletes them. |
- | When a macro or typedef is used in declaration or definition of an interrupt function using the __interrupt or __interrupt_brk keyword, the function name may be interpreted erroneously. Perform conversion after expanding the macro or typedef in advance. |
- | If there is a #pragma directive and a description of an interrupt function using a keyword for the same function, converting both of them into #pragma directives sometimes generates duplicate #pragma directives after conversion and a compile error will occur. In this case, delete the duplicate description. |
- | When omitting parameters of a function declaration in which the __interrupt or __interrupt_brk keyword is specified, a compile error will occur in the CC-RL. The void type has to be written as the parameter type. |
[Examples]
|
Pattern 1
|
Before conversion
|
#pragma vect INTP0 func sp=buff+10 rb1
void func(void) { }
|
|
After conversion
|
#pragma interrupt func(vect=INTP0, bank=RB1)
void func(void) { }
|
|
Pattern 2
|
Before conversion
|
#pragma interrupt INTP0 func leafwork1 rb1
void func(void) { }
|
|
After conversion
|
#pragma interrupt func(vect=INTP0, bank=RB1)
void func(void) { }
|
|
Pattern 3
|
Before conversion
|
__interrupt void func(void) { }
|
|
After conversion
|
#pragma interrupt func
void func(void) { }
|
|
Pattern 4
|
Before conversion
|
#pragma interrupt BRK_I func
void func(void) { }
|
|
After conversion
|
#pragma interrupt_brk func
void func(void) { }
|
|
Pattern 5
|
Before conversion
|
__interrupt void func1(void), func2(void);
|
|
After conversion
|
#pragma interrupt func1
void func1(void);
#pragma interrupt func2
void func2(void);
|
|
Pattern 6
|
Before conversion
|
#pragma interrupt INTP0 func
__interrupt func(void);
|
|
After conversion
|
#pragma interrupt func(vect=INTP0)
void func(void);
#pragma interrupt func
void func(void);
|
|
Corrective action
|
Duplicate #pragma directives will cause an error in the CC-RL. Delete one of the #pragma directives.
|
|
Pattern 7
|
Before conversion
|
typedef void func_t(void);
__interrupt func_t f1;
|
|
After conversion
|
typedef void func_t(void);
__interrupt func_t f1;
|
|
Corrective action
|
A compile error will occur in the CC-RL. Expand typedef or the macro in advance.
