Preliminary specification
Specifications in this manual are tentative and subject to change.
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 1.2.5 "Changing Interrupt Source" 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.
