H2B Statistics Registers
There are two sets of H2B Statistics registers – though both sets are accessible from Host as well as APE, each
side shall own a set. Set1 is owned by Host Driver and Set2 is owned by APE. HTX2B Stats Registers resides
in TX-MAC and the B2HRX Stats Registers reside in RDI. A counter is automatically reset to 0 by HW upon a
Read Operation by software. All counters roll over.
