Timer Counters (TCNT)

The timer counters (TCNT) are 16-bit counters, with one for each channel, for a total of five.

The TCNT are initialized to H'0000 by a power-on reset and when in standby mode. Manual reset

does not initialize TCNT. Accessing the TCNT counters in 8-bit units is prohibited. Always access

in 16-bit units.

Channel Abbreviation

Function

TCNT0

Increment counter

TCNT1

Increment/decrement counter*

TCNT2

Increment/decrement counter*

TCNT3

Increment/decrement counter*

TCNT4

Increment/decrement counter*

Notes: *1 Can only be used as an increment/decrement counter in phase counting mode, with

other channel overflow/underflow counting. It becomes an increment counter in all other

cases.

*2 Can only be used as an increment counter in complementary PWM mode. It becomes

an increment counter in all other cases.
