CHAPTER 8   16-BIT TIMER/EVENT COUNTER
8.4  16-Bit Timer/Event Counter Control Registers
The following seven types of registers are used to control the 16-bit timer/event counter.
• Timer clock select register 0 (TCL0)
• 16-bit timer mode control register (TMC0)
• Capture/compare control register 0 (CRC0)
• 16-bit timer output control register (TOC0)
• Port mode register 3 (PM3)
• External interrupt mode register 0 (INTM0)
• Sampling clock select register (SCS)
(1) Timer clock select register 0 (TCL0)
This register is used to set the count clock of the 16-bit timer register.
TCL0 is set with a 1-bit or 8-bit memory manipulation instruction.
RESET input sets TCL0 value to 00H.
Remark
TCL0 has the function of setting the PCL output clock in addition to that of setting the count clock
of the 16-bit timer register.
