Table 6. PMM Control and Status Bit Summary
NAME
LOCATION
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
PMR7, 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
PIP
STATUS.7
Status. 1 indicates a power-fail interrupt in service.
0
None
HIP
STATUS.6
Status. 1 indicates high priority interrupt in service.
0
None
LIP
STATUS.5
Status. 1 indicates low priority interrupt in service.
0
None
XTUP
STATUS.4
Status. 1 indicates that the crystal has stabilized.
1
None
SPTA1
STATUS.3
Status. Serial transmission on serial port 1.
0
None
SPRA1
STATUS.2
Status. Serial word reception on serial port 1.
0
None
SPTA0
STATUS.1
Status. Serial transmission on serial port 0.
0
None
SPRA0
STATUS.0
Status. Serial word reception on serial port 0.
0
