Operation Mode Selection
Operation modes and count modes are selected according to the setting of PWCS.
■
Operation Mode Selection
The following registers are used to set the selection of operation modes and count modes:
●
Operation mode setting: PWCSL:MOD2, MOD1, and MOD0 bits
Select the timer mode or pulse-width measurement mode to specify control of the count operation.
●
Count mode setting: PWCSL:S/C bit
Select single measurement or continuous measurement or reload operation or one-shot operation.
Table 16.6-1 lists the operation modes selected using the mode setting bits.
After reset, the one-shot timer is selected as an initial value.
Note:
Before the timer starts, always selects the operation mode.
