EM78P417N/418N/419N
8-Bit Microprocessor with OTP ROM
Bit 5 (PWM1E): PWM1 enable bit
0 = PWM1 is off (default value), and its related pin carries out the P51
function;
1 = PWM1 is on, and its related pin is automatically set to output.
Bit 4:
Unimplemented, read as ‘0’
Bit 3 (T1EN):
TMR1 enable bit
0 = TMR1 is off (default value)
1 = TMR1 is on
Bit 2 ~ Bit 0 (T1P2 ~ T1P0): TMR1 clock prescale option bits
