Carrier Modulator Transmitter (CMT) Block Description
8.5.8
When the microcontroller is in active background mode, the CMT temporarily suspends all counting until
the microcontroller returns to normal user mode.
8.6
The following registers control and monitor CMT operation:
8.6.1
The carrier generator data registers contain the primary and secondary high and low values for generating
the carrier output.

Primary Carrier High Time Data Values — When selected, these bits contain the number of input clocks
required to generate the carrier high and low time periods. When operating in time mode (see
“Time
Mode”), this register pair and the secondary register pair are alternatively selected under control of the
modulator. The primary carrier high and low time values are unaffected out of reset. These bits must be written
to nonzero values before the carrier generator is enabled to avoid spurious results.
