*1) When reading from clock and calendar counters, do not insert
stop condition until all times from second to year have been
read to prevent error in reading time.
*2) Take care so that process from start condition to stop condi-
tion will be completed within 0.5 seconds. (The RS5C372A/B
force access to the CPU to terminate within 0.5 to 1.0 sec-
onds after start condition has occurred in case the CPU is
failed during access.)
7.4 Second Digit Adjustment by ±30 seconds
Control register 2
←(00
×1×111) *1
*1) Write 1 to the ADJ bit. (The ±30 seconds of adjustment is
made within 122.1s (125s when 32.000kHz crystal is used)
after the ADJ bit is set to 1.)
7.5 Interrupt Operation
7.5-1 Periodic Interrupt Operation
CTFG=1?
Periodic interrupt operation

*1) The level mode is used for the periodic interrupt cycle select
bit.
*2) Interrupt to the CPU is cancelled by setting the CTFG bit to 0.
