ATAM893-D
Timer 1 Control Register 1 (T1C1)
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 supplied 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.
