37.6.2
C1TS—Offset 41h
Counter 1 Interval Time Status Byte Format. Counter 1 Interval Time Status Byte
Format. Status byte can be read following a Read Back Command. If latch status is
chosen (bit 4=0, Read Back Command) as a read back option for counter 1, the next
read from this register returns the status byte.
Access Method
Default: 00h
37.6.3
C2TS—Offset 42h
Counter 2 Interval Time Status Byte Format. Counter 2 Interval Time Status Byte
Format. Status byte can be read following a Read Back Command. If latch status is
chosen (bit 4=0, Read Back Command) as a read back option for counter 2, the next
read from this register returns the status byte.

Counter State (CS): When set, OUT of the counter is set. When cleared, OUT of the
counter is 0.

CR:
Count Register: When cleared, indicates when the last count written to the Count
Register (CR) has been loaded into the counting element (CE) and is available for
reading. The time this happens depends on the counter mode.

Read/Write Selection: These reflect the read/write selection made through
bits[5:4] of the control register. The binary codes returned during the status read match
the codes used to program the counter read/write selection. 00 Counter Latch
