Control Registers
35.3.21 DMM Pin Control 5 (DMMPC5)
This register allows to set individual pins to a logic low level without having to do a read-modify-write
operation as would be the case with the DMMPC3 register (Section 35.3.19). Writing a one to a bit will
change the output to a logic low level, writing a zero will not change the state of the pin.

Table 35-27. DMM Pin Control 5 (DMMPC5) Field Descriptions
Bit Field Value Description
31-19 Reserved 0 Reads returns 0. Writes have no effect.
18 ENACLR Sets output state of DMMENA pin to logic low. Value in the ENACLR bit clears the data output
control register bit to 0 regardless of the current value in the ENAOUT bit.
User and privilege mode (read):
0 Logic low (output voltage is V
OL
or lower)
1 Logic high (output voltage is V
OH
or higher)
User and privilege mode (write):
0 State of the pin is unchanged
1 Clears the pin to logic low (output voltage is set to V
OL
or lower)
17-2 DATAxCLR Sets output state of DMMDATA[x] pin to logic low. Value in the DATAxCLR bit clears the data
output control register bit to 0 regardless of the current value in the DATAxOUT bit.
User and privilege mode (read):
0 Logic low (output voltage is V
OL
or lower)
1 Logic high (output voltage is V
OH
or higher)
User and privilege mode (write):
0 State of the pin is unchanged
1 Clears the pin to logic low (output voltage is set to V
OL
or lower)
1 CLKCLR Sets output state of DMMCLK pin to logic low. Value in the CLKCLR bit clears the data output
control register bit to 0 regardless of the current value in the DATAxOUT bit.
User and privilege mode (read):
0 Logic low (output voltage is V
OL
or lower)
1 Logic high (output voltage is V
OH
or higher)
User and privilege mode (write):
0 State of the pin is unchanged
1 Clears the pin to logic low (output voltage is set to V
OL
or lower)
