Ethernet MMC transmit interrupt mask register (ETH_MMCTIMR)
Address offset: 0x0110
Reset value: 0x0000 0000
The Ethernet MMC transmit interrupt mask register maintains the masks for interrupts
generated when the transmit statistic counters reach half their maximum value. (MSB of the
counter is set). It is a 32-bit wide register.
Ethernet MMC transmitted good frames after a single collision counter
register (ETH_MMCTGFSCCR)
Address offset: 0x014C
Reset value: 0x0000 0000
This register contains the number of successfully transmitted frames after a single collision
in Half-duplex mode.

Bits 31:22 Reserved, must be kept at reset value.
Bit 21 TGFM: Transmitted good frames mask
Setting this bit masks the interrupt when the transmitted, good frames, counter reaches half
the maximum value.
Bits 20:16 Reserved, must be kept at reset value.
Bit 15 TGFMSCM: Transmitted good frames more single collision mask
Setting this bit masks the interrupt when the transmitted good frames after more than a
single collision counter reaches half the maximum value.
Bit 14 TGFSCM: Transmitted good frames single collision mask
Setting this bit masks the interrupt 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.
