MDEN
2:
The modulated output frequency can be greater and asynchronous from the clock that updates this
register bit, the bit value may not be valid for higher speed modulator or carrier signals.
MDBIT must be selected as the modulation source in the MDSRC register for this operation.
MDEN: Modulator Module Enable bit
1 = Modulator module is enabled and mixing input signals
0 = Modulator module is disabled and has no output
MDOE: Modulator Module Pin Output Enable bit
1 = Modulator pin output enabled
0 = Modulator pin output disabled
MDSLR: MDOUT Pin Slew Rate Limiting bit
1 = MDOUT pin slew rate limiting enabled
0 = MDOUT pin slew rate limiting disabled
MDOPOL: Modulator Output Polarity Select bit
1 = Modulator output signal is inverted
0 = Modulator output signal is not inverted
MDOUT: Modulator Output bit
Displays the current output value of the Modulator module.
Unimplemented: Read as ‘0’
MDBIT: Allows software to manually set modulation source input to module
1 = Modulator uses High Carrier source
0 = Modulator uses Low Carrier source

MDCON: MODULATION CONTROL REGISTER
W = Writable bit
x = Bit is unknown
‘0’ = Bit is cleared
