Remarks 1. The above interrupt response times are those during stabilized operation of the internal high-speed
oscillator (RSTS = 1).
2. RSTS: Bit 7 of the internal oscillation mode register (RCM)
(2) When high-speed system clock is used (normal model of C compiler)
Interrupt Response Time (
s (Max.))
RSTOP = 0, RSTS = 1

Note The longer value of the EEPROM write library interrupt response time becomes the Max. value, depending
on the value of fCPU.
Remarks 1. fCPU: CPU operation clock frequency
2. RSTOP: Bit 0 of the internal oscillation mode register (RCM)
3. RSTS: Bit 7 of the internal oscillation mode register (RCM)
