Register Description
17.4.1 GTCCR – General Timer/Counter Control Register
Bit 7 – TSM: Timer/Counter Synchronization Mode
Writing the TSM bit to one activates the Timer/Counter synchronization mode. In this mode, the value that is written to the
PSRASY and PSRSYNC bits is kept, hence keeping the corresponding prescaler reset signals asserted. This ensures that
the corresponding Timer/Counters are halted and can be configured to the same value without the risk of one of them
advancing during configuration. When the TSM bit is written to zero, the PSRASY and PSRSYNC bits are cleared by
hardware, and the Timer/Counters start counting simultaneously.
Bit 0 – PSRSYNC: Prescaler Reset
When this bit is one, Timer/Counter1 and Timer/Counter0 prescaler will be reset. This bit is normally cleared immediately by
hardware, except if the TSM bit is set. Note that Timer/Counter1 and Timer/Counter0 share the same prescaler and a reset
of this prescaler will affect both timers.
