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 31-4
Unimplemented: Read as ‘0’
bit 3
JTAGEN: JTAG Port Enable bit
1 = Enable the JTAG port
0 = Disable the JTAG port
bit 2
TROEN: Trace Output Enable bit
1 = Enable the trace port
0 = Disable the trace port
bit 1
Unimplemented: Read as ‘0’
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
