18.11.23 OCR3BH – Timer/Counter3 Output Compare Register B High Byte

Bit 7 6 5 4 3 2 1 0

Read/Write RW RW RW RW RW RW RW RW

Initial Value 0 0 0 0 0 0 0 0

The Output Compare Registers contain a 16-bit value that is continuously compared

with the counter value (TCNT3). A match can be used to generate an Output Compare

interrupt, or to generate a waveform output on the OC3B pin. The Output Compare

Registers are 16-bit in size. To ensure that both the high and low bytes are written

simultaneously when the CPU writes to these registers, the access is performed using

an 8-bit temporary High Byte Register (TEMP). This temporary register is shared by all

the other 16-bit registers. See section "Accessing 16-bit Registers" for details.
