*1) The level mode is used for the periodic
interrupt frequency select bit.
*2) Interrupt to the CPU may be released by
setting the CTFG bit to 0.
*1) Write 1 to the ADJ bit. (The ±30 seconds of
adjustment is made within 122.1 μs (125 μs when
32.000kHz crystal is used) after the ADJ bit is set to 1.
*1) When reading from clock and calendar registers, do not
insert stop condition until all times from second to year
have been read to prevent error in writing time.
*2) Take care so that process from start condition to stop
condition will be completed within 0.5 seconds. (The
RS5C372B forces access to the CPU to terminate within
0.5 to 1.0 seconds after start condition has occurred in
case the CPU is failed during access.)
