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.

REMOUT signal
T=1/fPUL = 12/fOSC [96/fOSC], T1/T = 1/2
T=1/fPUL = 12/fOSC [96/fOSC], T1/T = 1/3
T=1/fPUL = 8/fOSC [64/fOSC],
T1/T = 1/2
T=1/fPUL = 8/fOSC [64/fOSC],
T1/T = 1/4
T=1/fPUL = 11/fOSC [88/fOSC], T1/T = 4/11
No Pulse (same to D0~D9)
T=1/fPUL = 12/fOSC [96/fOSC], T1/T = 1/4
* Default value is ¡È0¡È
* [ ] means the value of ¡ÈT¡È, when Instruction cycle is fOSC/48
