MCGEN
Modulator and Carrier Generator Enable
Setting MCGEN will initialize the carrier generator and modulator and will enable all
clocks. When enabled, the carrier generator and modulator will function continuously.
When MCGEN is cleared, the current modulator cycle will be allowed to expire before
all carrier and modulator clocks are disabled to save power and the modulator output
is forced low.
NOTE: To prevent spurious operation, the user should initialize all data and control
registers before enabling the system.
