TYPE

ADDRESS

Read

0x01D0 2000

RBUF

Receive buffer DMA port address. Cycles through receive serializers, skipping over transmit

Accesses

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

XBUF

Transmit buffer DMA port address. Cycles through transmit serializers, skipping over receive
