U-1 U-1 R/WO-1 R/WO-1 U-1 U-0 R/WO-1 R/WO-1
— —FSCM1 FSCM0— — POSCMD1 POSCMD0
bit 7 bit 0
Legend: P = Programmable bit WO = Write-Once bit
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 7-6 Unimplemented: Read as ‘1’
bit 5-4 FSCM<1:0>: Clock Switching and Monitor Selection Configuration bits
1x = Clock switching is disabled, Fail-Safe Clock Monitor is disabled
01 = Clock switching is enabled, Fail-Safe Clock Monitor is disabled
00 = Clock switching is enabled, Fail-Safe Clock Monitor is enabled
bit 3-2 Unimplemented: Read as ‘0’
bit 1-0 POSCMD<1:0>: Primary Oscillator Configuration bits
11 = Primary Oscillator is disabled
10 = HS Oscillator mode is selected (10 MHz-40 MHz)
01 = MS Oscillator mode is selected (3.5 MHz-10 MHz)
00 = External Clock mode is selected
Note 1: The CONFIG3L bits can only be programmed indirectly by programming the Flash Configuration Word.
2: The CONFIG3L is reset to ‘1’ only on V
DD Reset; it is reloaded with the programmed value at any device
Reset.
