Questions answered in these manuals
Can the watchdog timeout period be adjusted?
Yes, the timeout periods for the watchdog and reset can be set individually by an external capacitor (Ctw).
From: Ricoh R5104V Series Microprocessor Power Management IC Datasheet
What is the difference between the 'A' and 'B' versions?
The 'A' version turns off the supervisor of clock input for the watchdog timer, while the 'B' version turns off all circuits to realize standby mode.
