Carrier Modulator Transmitter (CMT) Block Description

8.6.4
CMT Modulator Data Registers (CMTCMD1, CMTCMD2, CMTCMD3,
and CMTCMD4)
The modulator data registers control the mark and space periods of the modulator for all modes. The
contents of these registers are transferred to the modulator down counter and space period register upon
the completion of a modulation period.
1
EOCIE
End of Cycle Interrupt Enable — A CPU interrupt will be requested when EOCF is set if EOCIE is high.
0
CPU interrupt disabled
1
CPU interrupt enabled
0
MCGEN
Modulator and Carrier Generator Enable — Setting MCGEN will initialize the carrier generator and modulator
and enable all clocks. After it is 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. To prevent spurious operation, the user
should initialize all data and control registers before enabling the system.

Modulator and carrier generator disabled
