NOTES:

1. The IR bit in the INT2IC register may be set to “1” (interrupt requested) when the R1EDG bit is rewritten.

Refer to the paragraph 19.2.5 “Changing Interrupt Factor” in the Usage Notes Reference Book.

2. When TYS bit=1 (starts counting), the value set in the TYWC bit is valid. If TYWC bit=0, the timer Y count value is

written to both reload register and counter. If TYWC bit=1, the timer Y count value is written to the reload register

only.

When TYS bit=0 (stops counting), the timer Y count value is written to both reload register and counter regardless

of how the TYWC bit is set.
