USER’S MANUAL

NOT USED
RESET:
When STOP is set, the MCCI enters low-power stop mode. The system clock input to
the module is disabled. While STOP is set, only MMCR reads and writes are guaran-
teed to be valid. Only writes to other MCCI registers are guaranteed valid. The SCI re-
ceiver and transmitter must be disabled before STOP is set. To stop the SPI, set the
HALT bit in SPCR3, wait until the HALTA flag is set, then set STOP.
This bit has no effect because the CPU16 in the MCU operates only in supervisor
mode.
The IARB field is used to arbitrate between simultaneous interrupt requests of the
same priority. Each module that can generate interrupt requests must be assigned a
unique, non-zero IARB field value.
Used for factory test only.
The values of ILSCIA[2:0] and ILSCIB[2:0] in ILSCI determine the interrupt request
levels of SCIA and SCIB interrupts, respectively. Program this field to a value from $0
(interrupts disabled) through $7 (highest priority).
0 = MCCI clock operates normally.
1 = MCCI clock is stopped.
