■ RESTRICTIONS
Common in the series
Clock control block
Take the oscillation stabilization wait time during Low level input to INIT pin.
Bit search module
The bit search data register for 0-detection (BSD0) , and bit search data register for 1-detection (BSD1) , and
bit search data register for change point detection (BSDC) are only word-accessible.
I/O port
Ports are accessed only in bytes.
Low power consumption mode
To enter the standby mode, use the synchronous standby mode (set with the SYNCS bit as bit8 in TBCR, or
timebase counter control register) and be sure to use the following sequence :
Please do not do the following when the monitor debugger is used
Setting of the break point to the above instructions.
Execution of the single-stepping for the above instructions.
(ldi
#value_of_standby, r0)
(ldi
