Ethernet MMC receive interrupt mask register (ETH_MMCRIMR)
Address offset: 0x010C
Reset value: 0x0000 0000
The Ethernet MMC receive interrupt mask register maintains the masks for interrupts
generated when the receive statistic counters reach half their maximum value. (MSB of the
counter is set.) It is a 32-bit wide register.
Bit 15 TGFMSCS: Transmitted good frames more single collision status
This bit is set when the transmitted, good frames after more than a single collision, counter
reaches half the maximum value.
Bit 14 TGFSCS: Transmitted good frames single collision status
This bit is set when the transmitted, good frames after a single collision, counter reaches half
the maximum value.
Bits 13:0 Reserved, must be kept at reset value.

Bit 17 RGUFM: Received good unicast frames mask
Setting this bit masks the interrupt when the received, good unicast frames, counter reaches
half the maximum value.
Bits 16:7 Reserved, must be kept at reset value.
Bit 6 RFAEM: Received frames alignment error mask
Setting this bit masks the interrupt when the received frames, with alignment error, counter
reaches half the maximum value.
Bit 5 RFCEM: Received frame CRC error mask
Setting this bit masks the interrupt when the received frames, with CRC error, counter
reaches half the maximum value.
Bits 4:0 Reserved, must be kept at reset value.
