6.2 Configuration of 16-Bit Timer/Event Counter 00
16-bit timer/event counter 00 includes the following hardware.
Table 6-1. Configuration of 16-Bit Timer/Event Counter 00
Item Configuration
Time/counter 16-bit timer counter 00 (TM00)
Register 16-bit timer capture/compare registers 000, 010 (CR000, CR010)
Timer input TI000, TI010 pins
Timer output TO00 pin, output controller
Control registers
16-bit timer mode control register 00 (TMC00)
Capture/compare control register 00 (CRC00)
16-bit timer output control register 00 (TOC00)
Prescaler mode register 00 (PRM00)
Input switch control register (ISC)
Port mode register 3 (PM3)
Port register 3 (P3)
Remark When using 16-bit timer/event counter 00 as an external 24-bit event counter, 8-bit timer/event
counter 52 (TM52) and 8-bit timer counter H2 (TMH2) are used. For details, see 6.4.9 External 24-
bit event counter operation.
Figures 6-1 shows the block diagrams.

Cautions 1. The valid edge of TI010 and timer output (TO00) cannot be used for the P34 pin at the same
time. Select either of the functions.
