FUNCTION
RESET
WRITE ACCESS
XT/
RG
EXIF.3
Control. XT/
RG = 1, runs from crystal or external
clock; XT/
RG = 0, runs from internal ring oscillator.
X
0 to 1 only when
XTUP = 1 and
XTOFF = 0
RGMD
EXIF.2
Status. RGMD = 1, CPU clock = ring; RGMD = 0,
CPU clock = crystal.
0
None
CD1, CD0
PMR.7,
PMR.6
Control. CD1, 0 = 01, 4 clocks; CS1, 0 = 10, PMM1;
CD1, 0 = 11, PMM2.
0, 1
Write CD1, 0 = 10
or 11 only from
CD1, 0 = 01
SWB
PMR.5
Control. SWB = 1, hardware invokes switchback to 4
clocks, SWB = 0, no hardware switchback.
0
Unrestricted
XTOFF
PMR.3
Control. Disables crystal operation after ring is
selected.
0
1 only when
XT/
RG = 0
