Register 65 (MMC Receive Interrupt Register)
The MMC Receive Interrupt register maintains the interrupts that are generated when the following happens:
* Receive statistic counters reach half of their maximum values (0x8000_0000 for 32-bit counter and 0x8000 for 16-bit counter).
* Receive statistic counters cross their maximum values (0xFFFF_FFFF for 32-bit counter and 0xFFFF for 16-bit counter).
When the Counter Stop Rollover is set, then interrupts are set but the counter remains at all-ones. The MMC Receive Interrupt register is a 32-bit wide register. An interrupt bit is cleared when the respective MMC counter that caused the interrupt is read. The least significant byte lane (Bits[7:0]) of the respective counter must be read in order to clear the interrupt bit.
