REGISTER DESCRIPTION
0
WR
Indirect Write Holding Register, Bits 15:0
1
WR
Indirect Write Holding Register, Bits 31:16
2
WR
Indirect Write Address Register for Internal Target Register (Generates a write strobe to transfer contents of the
Write Holding Register into the Target Register specified by the Indirect Address, see also Tables of Indirect
Address Registers)
3
WR
Indirect Read Address Register (Used to select the Read source of data - uses the same register as Direct
Address 2 but generates a read strobe (for RAMs and AGC) as needed instead of a write strobe).
0
RD
Indirect Read, Bits 15:0
1
RD
Indirect Read, Bits 31:0
2
RD
Read Register (FIFO) - Reads FIFO data from output section (This location reads output data in the order
loaded in Global Control Indirect Address Registers F820-F83F. The FIFO is automatically incremented to the
next data location at the end of each read.)
