ATtiny4/5/9/10
Reusing the Temporary High Byte Register
TCCR0A – Timer/Counter0 Control Register A
Note:
The code example requires that the r17:r16 register pair contains the value to be written to
TCNT0.
If writing to more than one 16-bit register where the high byte is the same for all registers written,
then the high byte only needs to be written once. However, note that the same rule of atomic
operation described previously also applies in this case.
• Bits 7:6 – COM0A1:0: Compare Output Mode for Channel A
• Bits 5:4 – COM0B1:0: Compare Output Mode for Channel B
The COM0A1:0 and COM0B1:0 control the behaviour of Output Compare pins OC0A and
OC0B, respectively. If one or both COM0A1:0 bits are written to one, the OC0A output overrides
the normal port functionality of the I/O pin it is connected to. Similarly, if one or both COM0B1:0
bit are written to one, the OC0B output overrides the normal port functionality of the I/O pin it is
connected to.
Note, however, that the Data Direction Register (DDR) bit corresponding to the OC0A or OC0B
pin must be set in order to enable the output driver.
