Rear Input Data Register (Read Only) - (BAR0 + 0x301100)
The rear I/O can also be
configured as differential
channels with 2 global clock
signal pairs.
The rear input data register is used to access the individual input channels.
The rear input includes 32 LVCMOS single ended channels. Each channel is
controlled by a corresponding data bit as shown in the Rear Input Data
Register Table.
Channel input signal levels are determined by reading this register. Channel
output signals are set by writing to the rear output data register at base
address plus 0x301104.
This rear input data register is a read only register. Channel read operations
use 32-bit, 16-bit or 8-bit data transfers. All channels of this register are
fixed as input channels.
