ACCESS BYTE ACRONYM REGISTER DESCRIPTION
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 0x01D0 2000 XBUF Transmit buffer DMA port address. Cycles through transmit serializers, skipping over receive
Accesses 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.
