TCC/WDT Pre-Scaler
An 8-bit counter is available as prescaler for the TCC or WDT. The pre-scaler is available
only to either the TCC or WDT at a time.
An 8-bit counter is available for TCC or WDT as determined by the status of Bit 3 (PAB) of
CONT register.
The prescaler ratio is described in Section 6.2.2
CONT (Control Register)
.
The TCC/WDT circuit diagram is shown in Fig. 9 below.
Both TCC and prescaler are cleared by instructions.
The prescaler will be cleared by the WDTC and SLEP instructions when running in WDT
mode.
However, prescaler will not be cleared by SLEP instruction when running in TCC mode.
