36.3.16 DMM Pin Control 0 (DMMPC0)
This register defines if the DMM pins are used in functional or GIO mode. It should only be written when
ON/OFF = 0101 and the BUSY bit = 0 (Section 36.3.1). If pins other than the pins specified in Table 36-5
are configured, or DMMCLK and DMMSYNC are programmed as non-functional pins, no operation in
trace mode or direct data mode is possible.

Table 36-22. DMM Pin Control 0 (DMMPC0) Field Descriptions
Bit Field Value Description
31-19 Reserved 0 Reads returns 0. Writes have no effect.
18 ENAFUNC Functional mode of DMMENA pin. This bit defines whether the pin is used in functional mode or in
GIO mode.
User and privilege mode (read):
0 Pin is used in GIO mode.
1 Pin is used in Functional mode.
Privilege mode (write):
0 Pin is used in GIO mode.
1 Pin is used in Functional mode.
17-2 DATAxFUNC Functional mode of DMMDATA[x] pin. This bit defines whether the pin is used in functional mode or
in GIO mode. If pins are configured in functional mode, only pins defined in Table 36-5 have to be used
for proper operation.
User and privilege mode (read):
0 Pin is used in GIO mode.
1 Pin is used in Functional mode.
Privilege mode (write):
0 Pin is used in GIO mode.
1 Pin is used in Functional mode.
1 CLKFUNC Functional mode of DMMCLK pin. This bit defines whether the pin is used in functional mode or in
GIO mode.
User and privilege mode (read):
0 Pin is used in GIO mode.
1 Pin is used in Functional mode.
Privilege mode (write):
0 Pin is used in GIO mode.
1 Pin is used in Functional mode.
