Detailed Description

24 bit Counter for L1A ID of process FPGA

This module is a 24 bit Counter for L1A ID. The counter counts when it receives either a TTC L1A or a Software L1A.
This counter is reset by either TTC ECR or Software L1A Reset.
Software L1A Reset is selected when bit 1 of resister rdout_pulse_reg is set to 1.
The rdout_pulse_reg register is pulsed, and after 1 clock cycle the contents are reset to all Zeros.
