Table 35-25. DMM Pin Control 3 (DMMPC3) Field Descriptions (continued)
Bit Field Value Description
0 SYNCOUT Output state of DMMSYNC pin. This bit sets the pin to logic low or high level.
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 Logic low (output voltage is set to V
OL
or lower)
1 Logic high (output voltage is set to V
OH
or higher)
35.3.20 DMM Pin Control 4 (DMMPC4)
This register allows to set individual pins to a logic high 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 zero to a bit will
not change the state of the pin.

Bit Field Value Description
31-19 Reserved 0 Reads returns 0. Writes have no effect.
18 ENASET Sets output state of DMMENA pin to logic high. Value in the ENASET bit sets the data output
control register bit to 1 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 Logic high (output voltage is set to V
OH
or higher)
17-2 DATAxSET Sets output state of DMMDATA[x] pin to logic high. Value in the DATAxSET bit sets the data
output control register bit to 1 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 Logic high (output voltage is set to V
OH
or higher)
