Timer1: 8-bit Timer & PWM1 Period

The Timer1 is an 8-bit down-count timer which include latch register. Please refer to 2.3 for detail Timer

description.

The Timer1 can also be combined with Timer2 as PWM1 period and duty and controlled by the register

PWM1CON. Please refer to 2.4 for detail PWM description.

T1EN : TMR1 (PWM) Enable/Disable

= 1, TMR1 (PWM1) Enable.

= 0, TMR1 (PWM1) Disable.

T1LOAD : Enable/Disable Latch Buffer automatically load to counter register while writing to latch register

= 1, Enable TMR1 latch buffer automatically load to counter register while writing to latch register.

= 0, Disable TMR1 latch buffer automatically load to counter register while writing to latch register.

Note: This bit is only affected after latch register written. When the timer underflows, the latch register

data will automatically load into counter register.

T1EDG : TMR1 clock edge selection. This bit works only when external clock source TMCKI (IOB2) selected.

= 1, TMR1 increased on falling edge of TMCKI pin.

= 0, TMR1 increased on rising edge of TMCKI pin.
