Field : CMPFLGA

Counter Match occurred flag.

This bit indicates that the internal counter and SERRCNT value matched.

1'b0: read indicates match check of SERR interrupt on compare match is disabled.

1'b1: read indicates compare has matched. Write of one will clear the pending compare match. This will not de-assert the serr_req signal - software needs to write to serrpen bit to clear the interrupt.

When the match occurs, additional errors will not increment count until the compare status flag is cleared. If the software does not change the SERRCNT register prior to clearing this flag or reset the internal counter, next increment of internal counter could set this flag again in the next cycle.

Field : AUTOWB_DROP_FLG

Auto writeback counter match flag.

This bit indicates that the internal autoWB counter and autoWB_drop_cnt value matched.

1'b0: read indicates match check of hmi_intr interrupt on compare match is disabled.

1'b1: read indicates compare has matched. Write of one will clear the pending compare match. This will not de-assert the hmi_intr signal - software needs to write to hmi_intrpen bit to clear the interrupt.

When the match occurs, additional errors will not increment count until the compare status flag is cleared. If the software does not change the autoWB_drop_cnt register prior to clearing this flag or reset the autoWB counter, next increment of internal autoWB counter could set this flag in the next cycle.

Data Structure Documentation

struct ALT_ECC_HMC_OCP_MODSTAT_s

WARNING: The C register and register group struct declarations are provided for convenience and illustrative purposes. They should, however, be used with caution as the C language standard provides no guarantees about the alignment or atomicity of device memory accesses. The recommended practice for writing hardware drivers is to use the SoCAL access macros and alt_read_word() and alt_write_word() functions.
