R8C/11 Group
Timer Y, Z mode register
b7 b6 b5 b4 b3 b2 b1 b0
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 Source" 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 .
