Receive Pacer and Interrupt Combiner (RPIC)

The receive pacer and interrupt combiner (RPIC) block performs following functions:

Implements pacing for receive events.

Combines the output of the pacer module based on the settings of bits 16 to 23 in the EW_INTCTL
register and generates a single MACRXINT interrupt per the C64x+ megamodule.

Receives a single PS_TICK and forwards it to all the pacing blocks.

Allows, per interrupt enabling or disabling of the interrupts, the setting of bits 16 to 23 in the
EW_INTCTL register.
