T2XCLK Timer 2 External Clock Select.
This bit selects the external clock source for Timer 2. If Timer 2 is in 8-bit mode, this bit
selects the external oscillator clock source for both timer bytes. However, the Timer 2
Clock Select bits (T2MH and T2ML 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 RTC/8.
01: Capture trigger is RTC/8.
10: External Clock is SYSCLK/12.
11: External Clock is RTC/8.
