8  WATCHDOG TIMER (WDT2)

S1C17M12/M13 TECHNICAL MANUAL

 

Seiko Epson Corporation 

8-5

(Rev. 1.2)

Bits 9–0 

CMP[9:0]

 

These bits set the NMI/reset generation cycle.

 

The value set in this register is compared with the 10-bit counter value while WDT2 is running, and 

an NMI or reset is generated when they are matched.
