19.9.6 TC0 Output Compare Register A
Name: OCR0A
Offset: 0x47
Reset: 0x00
Property: When addressing as I/O register: address offset is 0x27
When addressing I/O registers as data space using LD and ST instructions, the provided offset must be
used. When using the I/O specific commands IN and OUT, the offset is reduced by 0x20, resulting in an
I/O address offset within 0x00 - 0x3F.

Bits 7:0 – OCR0A[7:0] Output Compare 0 A
The output compare register A contains an 8-bit value that is continuously compared with the counter
value (TCNT0). A match can be used to generate an output compare interrupt or to generate a waveform
output on the OC0A pin.
