Timer Clock Source
The timers are 16-bit up-counters. Minimum timeout delay is set by loading the value
0001H
to 1. Maximum timeout delay is set by loading the value
High and Low Byte registers, and setting the prescale value to 128. If the Timer reaches
FFFFH
The timer clock source can come from either the peripheral clock or the system clock.
Peripheral clock is based on a low frequency/low power 32 kHz secondary oscillator that
can be used with external watch crystal. Peripheral clock source is only available for
driving Timer and Noise Filter operation. It is not supported for other peripherals.
For timer operation in STOP Mode, peripheral clock must be selected as the clock source.
Peripheral clock can be selected as source for both ACTIVE and STOP mode operation.
System clock is only for operation in ACTIVE and HALT modes. System clock is
software selectable in Oscillator Control Module as external high frequency crystal or
internal precision oscillator. The TCLKS field in the Timer Control 2 register selects the
timer clock source.
