ACCESS TYPE

BYTE ADDRESS

ACRONYM

Read Accesses

0x01D0 2000

RBUF

Receive buffer DMA port address. Cycles through receive

serializers, skipping over transmit serializers and inactive

serializers. Starts at the lowest serializer at the beginning of each

time slot. Reads from DMA port only if XBUSEL = 0 in XFMT.

Write Accesses

0x01D0 2000

XBUF

Transmit buffer DMA port address. Cycles through transmit

serializers, skipping over receive and inactive serializers. Starts at

the lowest serializer at the beginning of each time slot. Writes to

DMA port only if RBUSEL = 0 in RFMT.
