JTAGEN: JTAG Port Enable bit⁽¹⁾
1 = JTAG port is enabled
0 = JTAG port is disabled
GCP: General Segment Program Memory Code Protection bit
1 = Code protection is disabled
0 = Code protection is enabled for the entire program memory space
GWRP: General Segment Code Flash Write Protection bit
1 = Writes to program memory are allowed
0 = Writes to program memory are disabled
DEBUG: Background Debugger Enable bit
1 = Device resets into Operational mode
0 = Device resets into Debug mode
Reserved: Program as ‘1’
Unimplemented: Read as ‘1’
ICS: Emulator Pin Placement Select bit
1 = Emulator/debugger uses EMUC2/EMUD2
0 = Emulator/debugger uses EMUC1/EMUD1
FWDTEN: Watchdog Timer Enable bit
1 = Watchdog Timer is enabled
0 = Watchdog Timer is disabled
WINDIS: Windowed Watchdog Timer Disable bit
1 = Standard Watchdog Timer is enabled
0 = Windowed Watchdog Timer is enabled; FWDTEN must be ‘1’
Unimplemented: Read as ‘1’
FWPSA: WDT Prescaler Ratio Select bit
1 = Prescaler ratio of 1:128
0 = Prescaler ratio of 1:32
Note 1: JTAGEN bit can not be modified using JTAG programming. It can only change using In-Circuit Serial
Programming™ (ICSP™).
