586 / 1158 page ![]() Section 10 16-Bit Timer Pulse Unit (TPU) Rev.1.00 Jun. 07, 2006 Page 534 of 1102 REJ09B0294-0100 10.3.6 Timer Counter (TCNT) TCNT is a 16-bit readable/writable counter. The TPU has six TCNT counters, one for each channel. TCNT is initialized to H'0000 by a reset or in hardware standby mode. TCNT cannot be accessed in 8-bit units. TCNT must always be accessed in 16-bit units.

The TPU has 16 TGR registers, four each for channels 0 and 3 and two each for channels 1, 2, 4, and 5. TGRC and TGRD for channels 0 and 3 can also be designated for operation as buffer registers. The TGR registers cannot be accessed in 8-bit units; they must always be accessed in 16-bit units. TGR and buffer register combinations during buffer operations are TGRA −TGRC and TGRB−TGRD.
