16-BIT PROGRAMMABLE TIMER

6.5
Timer during STOP mode
When the MCU enters STOP mode, the timer counter stops counting and remains at that
particular count value until STOP mode is exited by an interrupt. If STOP mode is exited by
power-on or external reset, the counter is forced to $FFFC but if it is exited by an interrupt then
the counter resumes from its stopped value.
Another feature of the programmable timer is that if at least one valid input capture edge occurs
at one of the TCAP pins while in STOP mode, the corresponding input capture detect circuitry is
armed. This action does not wake the MCU or set any timer ags, but when the MCU does
wake-up there will be an active input capture ag (and data) from that rst valid edge which
occurred during STOP mode.
If STOP mode is exited by an external reset then no such input capture ag or data action takes
place even if there was a valid input capture edge (at one of the TCAP pins) during STOP mode.
6.6
Timer during WAIT mode
The CPU clock halts during WAIT mode, but the timer keeps running. If a reset is used to exit WAIT
mode the counters are forced to $FFFC. If interrupts are enabled, a timer interrupt will cause the
processor to exit WAIT mode.
6.7
Timer state diagrams
The relationships between the internal clock signals, the counter contents and the status of the
ag bits are shown in Figure 6-2 to Figure 6-5. It should be noted that the signals labelled ‘internal’
(processor clock, timer clocks and reset) are not available to the user.
