Figure 31. Timer/Counter0 Block Diagram
Timer/Counter0 Control Register - TCCR0
•
These bits are reserved bits in the AT90S2333/4433 and always read as zero.
•
The Clock Select0 bits 2,1, and 0 define the prescaling source of Timer0.
Table 9. Clock 0 Prescale Select
The Stop condition provides a Timer Enable/Disable function. The prescaled CK modes are scaled directly from the CK
oscillator clock. If the external pin modes are used, for Timer/Counter0, transitions on PD4/(T0) will clock the counter even
if the pin is configured as an output. This feature can give the user SW control of the counting.
