Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 31-14 Unimplemented: Read as ‘0
bit 13 IOLOCK: Peripheral Pin Select Lock bit
(1)
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.
bit 12 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.
