EDK Input/Output Registers (Read/Write) –
(P 8004H)

The AXM-VFX-EDK LVTTL channels may be individually accessed via

this register at the carrier P 8004H. This includes all 30 general
purpose LVTTL channels on the AXM-VFX-EDK. Each channel is
controlled by its corresponding data bit, as shown in the register mapping
table below. Channel input signal levels are determined by reading this
register. Likewise, channel output signal levels are set by writing to this
register. Note that the data direction, input or output, must first be set via
the Differential Direction register at PCIBAR2 plus 8008H.

Channel read/write operations use 8-bit, 16-bit, or 32-bit data transfers

with the lower ordered bits corresponding to the lower-numbered channels
for the register of interest. All input/output channels are configured as inputs
following a power-on or software reset. Data-bits 30 and 31 are not used
and will return 0 when read. Data bits 0 through 7 in the AXM-D03 module
will read back the last data values written to those bits.
