Mask CD Interrupt
MCDxC = 0
MCDxC = 1*
CDxC bit is NOT MASKED
CDxC bit is MASKED
x
Bit number (A or B)
C
Channel number (1 through 4)
Masked: A change does not cause the Interrupt Pin to go Low.
This command does not depend on the state of the Channel Enable Register.
* Power Up and Hardware Reset (RST) Value = FFh.
