EM78P350N
8-Bit Microprocessor with OTP ROM
6.11.3 Programming the Related Registers
When defining TMRX, refer to the related registers of its operation as shown in the
table below. It must be noted that the PWMX bits must be disabled if their related
TMRXs are employed. That is, Bit 7 ~ Bit 5 of the PWMCON register must be set to ‘0’.

6.11.4 Timer Programming Process/Steps
1. Load PRDX with the TIMER duration
2. Enable interrupt function by writing IOCF, if required
3. Load a desired a TMRX prescaler value to PWMCON and TMRCON and enable
TMRX and disable PWMX
6.12 Comparator
EM78P350N has one comparator comprising of two analog inputs and one output. The
comparator can be utilized to wake up the EM78P350N from sleep mode. The
