12 – 26
OPTION B (D): 1.5 V (3.0 V), With regulator
circuit for LCD bias
OPTION A (C): 1.5 V (3.0 V), Without regulator
circuit for LCD bias
12.5.2 Selecting Receive Data LSB/MSB First
When the LSB is first in receive data, set SRLMB (bit 3 of SRCON1) to “0”.
If the MSB is first, set SRLMB to “1”.
The correspondence between receive data and SRBUFL/H bits for LSB first receive is shown in Figure 12-13, and
for MSB first receive in Figure 12-14.
