Timer 3 High Byte Overflow Flag.
Set by hardware when the Timer 3 high byte overflows from 0xFF to 0x00. In 16 bit
mode, this will occur when Timer 3 overflows from 0xFFFF to 0x0000. When the
Timer 3 interrupt is enabled, setting this bit causes the CPU to vector to the Timer 3
interrupt service routine. This bit is not automatically cleared by hardware.
Timer 3 Low Byte Overflow Flag.
Set by hardware when the Timer 3 low byte overflows from 0xFF to 0x00. TF3L will
be set when the low byte overflows regardless of the Timer 3 mode. This bit is not
automatically cleared by hardware.
Timer 3 Low Byte Interrupt Enable.
When set to 1, this bit enables Timer 3 Low Byte interrupts. If Timer 3 interrupts are
also enabled, an interrupt will be generated when the low byte of Timer 3 overflows.
Timer 3 Comparator 1/External Oscillator Capture Enable.
When set to 1, this bit enables Timer 3 Capture Mode.
Timer 3 Split Mode Enable.
When this bit is set, Timer 3 operates as two 8-bit timers with auto-reload.
0: Timer 3 operates in 16-bit auto-reload mode.
1: Timer 3 operates as two 8-bit auto-reload timers.
Timer 3 Run Control.
Timer 3 is enabled by setting this bit to 1. In 8-bit mode, this bit enables/disables
TMR3H only; TMR3L is always enabled in split mode.
This bit selects the “external” and “capture trigger” clock sources for Timer 3. If
Timer 3 is in 8-bit mode, this bit selects the “external” clock source for both timer
bytes. Timer 3 Clock Select bits (T3MH and T3ML in register CKCON) may still be
used to select between the “external” clock and the system clock for either timer.
Note: External clock sources are synchronized with the system clock.
00: External Clock is SYSCLK /12. Capture trigger is Comparator 1.
01: External Clock is External Oscillator/8. Capture trigger is Comparator 1.
10: External Clock is SYSCLK/12. Capture trigger is External Oscillator/8.
11: External Clock is Comparator 1. Capture trigger is External Oscillator/8.
