T48C862-R4 [Preliminary]
* Bit 3 -> MSB, Bit 0 -> LSB
The three bits T1C[2:0] select the divider for Timer 1. The resulting time interval
depends on this divider and the Timer 1 input clock source. The timer input can be sup-
plied by the system clock, the 32-kHz oscillator or via the clock management. If the clock
management generates the SUBCL, the selected input clock from the RC oscillator, 4-
MHz oscillator or an external clock is divided by 16.
