ST72344xx ST72345xx
Counter low register (CLR)
Reset value: 1111 1100 (FCh)
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)
Reset value: 1111 1111 (FFh)
This is an 8-bit register that contains the high part of the counter value.
Alternate counter low register (ACLR)
Reset value: 1111 1100 (FCh)
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)
Reset value: Undefined
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)
Reset value: Undefined
This is an 8-bit read only register that contains the low part of the counter value (transferred
by the Input Capture 2 event).
