8.22.3 SCTimer/PWM in the large configuration (SCT0/1)
Remark: For applications that require exact timing of the SCT outputs (for example
PWM), assign the outputs only to fixed-pin functions to ensure that the output skew is
nearly the same for all outputs.
8.22.3.1 Features
The following feature list summarizes the configuration for the two large SCTs. Each large
SCT has a companion small SCT (see Section 8.22.4
) with fewer inputs and outputs and
a reduced feature set.
• Each SCT supports:
– 16 match/capture registers
– 16 events
– 16 states
– Match register 0 to 5 support a fractional component for the dither engine
