Caution
(4) Prescaler mode register 00 (PRM00)
This register is used to set the 16-bit timer counter 00 (TM00) count clock and the TI000, TI010 pin input valid
edges.
PRM00 is set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation sets the value of PRM00 to 00H.
Remarks 1. f
Note The external clock requires a pulse longer than two cycles of the internal count clock (f
Cautions 1. Always set data to PRM00 after stopping the timer operation.
Address: FF61H After reset: 00H R/W
PRM00
Symbol
6. When the TOE00 is 0, set the TOE00, LVS00, and LVR00 at the same time with the 8-bit
memory manipulation instruction. When the TOE00 is 1, the LVS00 and LVR00 can be set
with the 1-bit memory manipulation instruction.
2. ( ): f
2. If the valid edge of the TI000 pin is to be set as the count clock, do not set the clear/start
XP
mode and the capture trigger at the valid edge of the TI000 pin.
