EM78P350N
8-Bit Microprocessor with OTP ROM
Only one of Cases 1 to 5 can be enabled before entering into sleep mode. That is:
Case [a] If WDT is enabled before SLEP, all of the RE bit is disabled. Hence, the
EM78P350N can be awakened only with Case 1 or Case 2. Refer to the
section on Interrupt (Section 6.7) for further details.
Case [b] If Port 6 Input Status Change is used to wake -up the EM78P350N and ICWE
bit of RE register is enabled before SLEP, WDT must be disabled. Hence,
the EM78P350N can be awakened only with Case 3. Wake-up time is
dependent on oscillator mode. In RC mode the reset time is 32 clocks (for
stable oscillators).
In High Crystal mode, reset time is 2ms and 32 clocks (for stable oscillators);
and in low Crystal mode, the reset time is 500ms.
Case [c] If Comparator output status change is used to wake-up the EM78P350N and
the CMPWE bit of the RE register is enabled before SLEP, WDT must be
disabled by software. Hence, the EM78P350N can be awakened only with
Case 4.
Wake-up time is dependent on oscillator mode. In RC mode, the reset time is
32 clocks (for stable oscillators). In High crystal mode, reset time is 2ms and
32 clocks (for stable oscillators), and in low crystal mode, the reset time is
500ms.
Case [d] If AD conversion completed is used to wake-up the EM78P350N and the
ADWE bit of the RE register is enabled before SLEP, WDT must be disabled
by software. Hence, the EM78P350N can be awakened only with Case 5.
The wake-up time is 15 TAD (ADC clock period).
Wake-up time is dependent on oscillator mode. In RC mode, the reset time is
32 clocks (for stable oscillators). In High crystal mode, reset time is 2ms and
32 clocks (for stable oscillators); and in low crystal mode, the reset time is
500ms.
Case [e] If PWM/Timer output status change is used to wake-up the EM78P350N and
the PWMWE bit of the RE register is enabled before Idle mode (except in
sleep mode), WDT must be disabled by software. Hence, the EM78P350N
can be awakening only with Case 6.
Wake-up time is dependent on the oscillator mode. In RC mode the reset
time is 32 clocks (for stable oscillators). In High crystal mode, reset time is
2ms and 32 clocks (for stable oscillators); and in low crystal mode, the reset
time is 500ms.
