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 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.
3. The INT2 interrupt request is not generated when the TYMOD0 bit is set to “1” (programmable waveform generatio mode).
