Section 17 16-Bit Timer Pulse Unit (TPU)
Rev. 2.00 Mar 09, 2006 page 688 of 906
REJ09B0292-0200
The TCR registers are 8-bit registers that control the TCNT channels. The TPU has three TCR
registers, one for each of channels 0 to 2. The TCR registers are initialized to H'00 by a reset.
TCNT operation should be stopped when making TCR settings.
Bits 7 to 5—Counter Clear 2 to 0 (CCLR2 to CCLR0): These bits select the TCNT counter
clearing source.

Notes: 1. Synchronous operation setting is performed by setting the SYNC bit in TSYR to 1.
2. When TGRC or TGRD is used as a buffer register, TCNT is not cleared because the
buffer register setting has priority, and compare match/input capture does not occur.
3. Bit 7 is reserved in channels 1and 2. It is always read as 0. The write value should
always be 0.
