To readback register R3 perform the
following steps:
- Write R31 with READBACK_ADDR = 3.
DATAuWire and CLKuWire are toggled as shown in Figure 5-1 with new
data being clocked in on rising edges of CLKuWire
- Toggle LEuWire high and low as
shown in Figure 5-1.
- Toggle CLKuWire high and then low
32 times to read back all 32 bits of register R3. Data is read MSB first. Data
is valid on falling edge of CLKuWire.
