MMC_Transmit_Interrupt

The MMC Transmit Interrupt register maintains the interrupts generated when transmit statistic counters reach half of their maximum values (0x8000_0000 for 32-bit counter and 0x8000 for 16-bit counter), and the maximum values (0xFFFF_FFFF for 32-bit counter and 0xFFFF for 16-bit counter). When Counter Stop Rollover is set, then interrupts are set but the counter remains at all-ones. The MMC Transmit 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.
