(4) Prescaler mode register 0n (PRM0n)
Note The external clock requires a pulse two cycles longer than internal clock (f
This register is used to set the 16-bit timer counter 0n (TM0n) count clock and TI000 and TI010 pin input valid
edges.
PRM0n can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation sets PRM0n to 00H.
