Legend:
R = Readable bit
-n = Value at POR
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
x = Bit is unknown
bit 31-14 Unimplemented: Read as ‘0’
bit 13 IOLOCK: Peripheral Pin Select Lock bit⁽¹⁾
bit 12
1 = Peripheral Pin Select is locked. Writes to PPS registers is not allowed.
0 = Peripheral Pin Select is not locked. Writes to PPS registers is allowed.
PMDLOCK: Peripheral Module Disable bit⁽¹⁾
1 = Peripheral module is locked. Writes to PMD registers is not allowed.
0 = Peripheral module is not locked. Writes to PMD registers is allowed.
bit 11-4 Unimplemented: Read as ‘0’
bit 3
JTAGEN: JTAG Port Enable bit
1 = Enable the JTAG port
0 = Disable the JTAG port
bit 2-1 Unimplemented: Read as ‘1’
bit 0
TDOEN: TDO Enable for 2-Wire JTAG
1 = 2-wire JTAG protocol uses TDO
0 = 2-wire JTAG protocol does not use TDO
Note 1: To change this bit, the unlock sequence must be performed. Refer to Section 6. “Oscillator” (DS61112)
in the “PIC32 Family Reference Manual” for details.
