(at wake-up function)
• m is CS4 bit and CS3 bit (bit 4 and bit 3) of clock control register (ICCR0) .
• n is CS2 bit to CS0 bit (bit 2 to bit 0) of clock control register (ICCR0) .
• Actual timing of I
• Standard-mode :
• Fast-mode :
ICCR0 register.
m and n can be set at the range : 0.9 MHz < t
Setting of m and n limits the machine clock that can be used below.
m and n can be set at the range : 3.3 MHz < t
Setting of m and n limits the machine clock that can be used below.
