INTCH). To enable the counting operation, the
timer on bit (TON ; bit 4 of TMR2C) should be
set to "1".
For proper operation, bit 6 of TMR2C should be
set to "1", and bit3, bit7 should be set to "0".
Timer 2 can also be used as a buzzer output by
setting PB.0 and AUD to be PWM1 and PWM2
output respectively by mask option. When the
PWM1/PWM2 is selected, setting 2FH.6/2FH.7
to "1" will select PFD/PFDB output and setting
2FH.6/2FH.7 to "0" will select PWM1/PWM2
output. When the PFD/PFDB function is se-
lected, setting 2FH.4/2FH.5 to "1" will enable
PFD/PFDB output and setting 2FH.4/2FH.5 to
"0" will disable PFD/PFDB output. PFD Fre-
quency= T2f/ [(256-TMR2) 2].
