Output compare 2 low register (OC2LR)
This is an 8-bit register that contains the low part of the value to be compared to the CLR
register.
Counter high register (CHR)
This is an 8-bit register that contains the high part of the counter value.
Counter low register (CLR)
This is an 8-bit register that contains the low part of the counter value. A write to this register
resets the counter. An access to this register after accessing the CSR register clears the
TOF bit.
Alternate counter high register (ACHR)
This is an 8-bit register that contains the high part of the counter value.
