Control registers
Table 6-1. Configuration of 16-Bit Timer/Event Counter 00
Configuration
16-bit timer counter 00 (TM00)
16-bit timer capture/compare registers 000, 010 (CR000, CR010)
TI000, TI010 pins
TO00 pin, output controller
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.
