Counter high register (CHR)
Reset value: 1111 1111 (FFh)
This is an 8-bit read-only register that contains the high part of the counter value.
Counter low register (CLR)
Reset value: 1111 1100 (FCh)
This is an 8-bit read-only 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 read-only 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 read-only 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.
