EMAC_TRP_H
EMAC Transmit Read Pointer Register—High Byte
Because of the size of the EMAC’s 8 KB SRAM, the upper three bits of the EMAC Trans-
mit Read Pointer Register are always zero. See
EMAC Receive Blocks Left Register—Low and High Bytes
This register reports the number of buffers left in the Receive EMAC shared memory. The
hardware uses this information along with the block-level set in the EMAC_BUFSZ regis-
ter to determine when to transmit a pause control frame. Software uses this information to
determine when it must request that a pause control frame be transmitted (by setting bit 6
of the EMAC_CFG4 register). For the BlksLeft logic to operate properly, the Receive
buffer must contain at least one more packet buffer than the number of packet buffers
required for the largest packet. That is, one packet cannot fill the entire Receive buffer.
Otherwise, the BlksLeft will be in error. See
