2.14.4 Range of measurable time

There is a finite range of measurable time for timer measurements by Run-Break timer events (see "2.14.2 Measuring execution time from start to stop") or timer measurement events (see "2.14.3 Measuring execution time in a section"), as shown below.

Table 2.16

Range of Measurable Time

Debug tool	Run-Break timer event		Timer measurement event
E1(Serial)/E1(JTAG)/ E20(Serial)/E20(JTAG) [RX600, RX700 Series]	Min	100 microseconds	Min	-
	Max	Approx. 72 hours	Max	Depends on CPU clock frequency 32-bit counter x 2 channels or 64-bit counter x 1 channel Overflow detection available
E1(Serial)/E1(JTAG)/ E20(Serial)/E20(JTAG) [RX200 Series, RX140 Group]	Min	100 microseconds	Min	-
	Max	Approx. 72 hours	Max	Depends on CPU clock frequency 24-bit counter x 1 channel Overflow detection available
Simulator	Depends on CPU clock frequency 64-bit counter Overflow detection available		Depends on CPU clock frequency 64-bit counter Overflow detection available
