SPI Bus Interface

2 SPI BUS INTERFACE
2.1 Pin Descriptions
2.2 SPI Operation Description
The serial data bits are organized into a field
containing 8 bits of data as shown in
Table 1
. The
DATA 0 to DATA 2 bits determine the output
mode of the TS4855 as shown in
Table 2
. The
DATA 3 to DATA 7 bits determine the gain level
setting as illustrated by
Table 3
. For each SPI
transfer, the data bits are written to the DATA pin
with the least significant bit (LSB) first. All serial
data are sampled at the rising edge of the CLK
signal. Once all the data bits have been sampled,
ENB transitions from logic-high to logic low to
complete the SPI sequence. All 8 bits must be
received before any data latch can occur. Any
excess CLK and DATA transitions will be ignored
after the height rising clock edge has occurred.
For any data sequence longer than 8 bits, only the
first 8 bits will get loaded into the shift register and
the rest of the bits will be disregarded.
