When this option is omitted, it does not generate the saved and restored code of the accumulator (ACC,ACC0,ACC1) for interrupt functions.
This option generates the saved and restored code of the accumulator (ACC,ACC0,ACC1) for interrupt functions. |
The save and restored code of the ACC when the ISA *1 is selected as the RXv1 or the microcomputer type is selected by the CPU *2. |
*1) This means a selection by the -isa option or the ISA_RX environment variable.
*2) This means a selection by the -cpu option or the CPU_RX environment variable.
The generated saved and restored code is the same code generated when acc is selected in #pragma interrupt. For the actual saved and restored code, refer to the description of acc and no_acc in #pragma interrupt of #pragma Extension Specifiers and Keywords. |
