Data Transfer Format
Figure 10.4 and figure 10.5 show the SCI2 data transfer format. Data is sent and received starting
from the least significant bit, in LSB-first format. Transmit data is output from one falling edge of
the serial clock until the next falling edge. Receive data is latched at the rising edge of the serial
clock.
When SCI2 operates on an internal clock, a gap can be inserted between each byte of transferred
data and the next, as shown in figure 10.5. During this gap, pin SCK 2 output remains high. Also, a
strobe pulse can be output at pin STRB.
The length of the gap is designated in bits GAP1 and GAP0 in serial control register 2 (SCR2).
