Field Function
INUSE 0 - Peripheral is not being used.
1 - Peripheral is being used.
28-27
—
This read-only bit field is reserved and always has the value 0.
26-24
PCS
This read/write bit field is used for peripherals that support various clock selections.
This field can only be written when the CGC bit is 0 (clock disabled). Likewise, if the INUSE flag is set,
this field is locked.
000 - Clock is off (or test clock is enabled) An external clock can be enabled for this peripheral.
001 - OSCCLK - System Oscillator Platform Clock.
010 - SCGIRCLK - Slow IRC Clock.
011 - SCGFIRCLK - Fast IRC Clock.
100 - Reserved.
101 - Reserved.
110 - SCGPCLK System PLL clock .
111 - Reserved.
23-4
—
This read-only bit field is reserved and always has the value 0.
3
FRAC
This read/write bit field sets the fraction multiply value for the fractional clock divider used as a clock
source. Divider output clock = Divider input clock x [(FRAC+1)/(DIV+1)].
This field can only be written when the CGC bit is 0 (clock disabled). Likewise, if the INUSE flag is set,
this field is locked.
0 - Fractional value is 0.
1 - Fractional value is 1.
2-0
PCD
This read/write bit field is used for peripherals that require a clock divider. At SOC integration, each
peripheral is assigned either a divider or not.
This field can only be written when the CGC bit is 0 (clock disabled). Likewise, if the INUSE flag is set,
this field is locked.
000 - Divide by 1 (pass-through, no clock divide).
001 - Divide by 2.
010 - Divide by 3.
011 - Divide by 4.
100 - Divide by 5.
101 - Divide by 6.
110 - Divide by 7.
111 - Divide by 8.
