Starting with CLB Type 2, the Counter module can operate as a serializer. In this mode of operation, this module acts as a shift register (also referred to as a serializer). In serializer mode of operation, the EVENT input is used to shift one bit of data into the serializer. Either of MATCH1 and MATCH2 can be configured to send out the shift register data.Using the MATCH1/2_TAP_SEL bit of CLB_COUNT_MATCH_TAP_SEL, any bit position of the counter can be brought out on the MATCH1/MATCH2 outputs. The shifting and direction of the counter in this mode is controlled by MODE_0 (enable) and MODE_1 (direction).
To enable the Serializer mode, CLB_MISC_CONTROL.COUNT_SERIALIZER_0 (for Counter 0) must be set.
