bit 1
bit 0
Unimplemented: Read as â0â
XINST: Extended Instruction Set Enable bit
1 = Instruction set extension and Indexed Addressing mode are enabled
0 = Instruction set extension and Indexed Addressing mode are disabled (Legacy mode)
Unimplemented: Read as â0â
SOSCSEL<1:0>: SOSC Power Selection and Mode Configuration bits
11 = High-power SOSC circuit selected
10 = Digital (SCLKI) mode; I/O port functionality of RC0 and RC1 enabled
01 = Low-power SOSC circuit selected
00 = Reserved
INTOSCSEL: LF-INTOSC Low-power Enable bit
1 = LF-INTOSC in High-Power mode during Sleep
0 = LF-INTOSC in Low-Power mode during Sleep
Unimplemented: Read as â0â
RETEN: VREG Sleep Enable bit
1 = Regulator power while in Sleep mode is controlled by VREGSLP (WDTCON<7>)
0 = Regulator power while in Sleep mode is controlled by SRETEN (WDTCON<4>). Ultra low-power
regulator is enabled.
