Chapter 4. FUNCTIONAL DESCRIPTION
Pulse Generator
The following frequency and duty ratio are selected for carrier signal outputted
from the REMOUT port depending on a PMR (Pulse Mode Register) value set in
a program.
T
T1
PMR
REMOUT signal
T=1/fPUL = 12/fOSC [96/fOSC], T1/T = 1/2
T=1/fPUL = 12/fOSC [96/fOSC], T1/T = 1/3
0
1
2
T=1/fPUL = 8/fOSC [64/fOSC],
T=1/fPUL = 8/fOSC [64/fOSC],
T1/T = 1/2
T1/T = 1/4

4
T=1/fPUL = 11/fOSC [88/fOSC], T1/T = 4/11
No Pulse (same to D0 ~ D9)

6
T=1/fPUL = 12/fOSC [96/fOSC], T1/T = 1/4
No pulse (same to D0 ~ D9)

* Default value is "0"
* [ ] means the value of "T", when Instruction cycle is fOSC/48 in MHz version
