13.2. Timer 1
Timer 1 is a 16-bit timer formed by two 8-bit SFRs: TMR1L (low byte) and TMR1H (high byte). Timer 1 operates in
16-bit auto-reload mode and is clocked by the system clock divided by 12 or SmaRTClock divided by 8. As the 16-
bit timer register increments and overflows from 0xFFFF to 0x0000, the 16-bit value in the Timer 1 reload registers
(TMR1RLH and TMR1RLL) is loaded into the Timer 1 register as shown in Figure 13.1, and the Timer 1 Overflow
Flag (INT1.3) is set. If Timer 1 interrupts are enabled (if IN1EN.3 is set), an interrupt will be generated on each
Timer 1 overflow. Additionally, if Timer 1 interrupts are enabled and the TF0LEN bit is set (TMR0CN.5), an interrupt
will be generated each time the lower 8 bits (TMR0L) overflow from 0xFF to 0x00.
