Bit 2: Reset on Read (ROR) – When set to 1, each management counter will reset to zero after a read access of
the least-significant byte. When equal to zero, the counters will only be reset by the CRST bit.
Bit 1: Counter Stop Rollover (CSR) – When set to 1, each counter will saturate at the maximum value and not roll
over. When equal to zero, each counter can rollover to zero after the maximum value is exceeded.
Bit 0: Counter Reset (CRST) – Set to 1 to initiate a reset of all management counters. Set to zero for normal
operation.
0 = Normal operation.
