24.8.2 MMC
receive
interrupt register
The MMC receive interrupt register maintains the interrupts generated when receive statistic
counters reach half their maximum values. (MSB of the counters is set.) It 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.
