PLLPOST<1:0>
This bit is cleared when the ROI bit is set and an interrupt occurs.
This register resets only on a Power-on Reset (POR).
DOZE<2:0> bits can only be written to when the DOZEN bit is clear. If DOZEN = 1, any writes to
DOZE<2:0> are ignored.
The DOZEN bit cannot be set if DOZE<2:0> = 000. If DOZE<2:0> = 000, any attempt by user software to
set the DOZEN bit is ignored.
ROI: Recover on Interrupt bit
1 = Interrupts will clear the DOZEN bit and the processor clock and peripheral clock ratio is set to 1:1
0 = Interrupts have no effect on the DOZEN bit
DOZE<2:0>: Processor Clock Reduction Select bits
111 = F
110 = F
101 = F
100 = F
011 = F
010 = F
001 = F
000 = F
DOZEN: Doze Mode Enable bit
1 = DOZE<2:0> field specifies the ratio between the peripheral clocks and the processor clocks
0 = Processor clock and peripheral clock ratio forced to 1:1
FRCDIV<2:0>: Internal Fast RC Oscillator Postscaler bits
111 = FRC divided by 256
110 = FRC divided by 64
101 = FRC divided by 32
100 = FRC divided by 16
011 = FRC divided by 8
010 = FRC divided by 4
001 = FRC divided by 2
000 = FRC divided by 1 (default)
PLLPOST<1:0>: PLL VCO Output Divider Select bits (also denoted as ‘N2’, PLL postscaler)
11 = Output divided by 8
10 = Reserved
01 = Output divided by 4 (default)
00 = Output divided by 2
