Alternate counter low register (ACLR)
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 an access to CSR register does not clear
the TOF bit in the CSR register.
Input capture 2 high register (IC2HR)
This is an 8-bit read only register that contains the high part of the counter value (transferred
by the Input Capture 2 event).
Input capture 2 low register (IC2LR)
This is an 8-bit read only register that contains the low part of the counter value (transferred
by the Input Capture 2 event).
