The watch timer has the following five selectors.
• Selector that selects one of f
• Selector that selects the main clock (f
• Selector that selects f
• Selector that selects 2
• Selector that selects 2
This is an 8-bit compare register that sets the interval time.
This register controls clock supply to the watch timer.
This is an 8-bit register that controls the operation of the watch timer/interval timer, and sets the interrupt
request signal generation interval.
