2.6
The SCLK pin is used as a clock input pin and the
SDATA pin is used for entering command bits and data
input/output during serial operation. Commands and
data are transmitted on the rising edge of SCLK,
latched on the falling edge of SCLK, and are Least
Significant bit (LSb) first.
2.6.1
All instructions are 20 bits, consisting of a leading 4-bit
command followed by a 16-bit operand, which depends
on the type of command being executed. To input a
command, SCLK is cycled four times. The commands
needed for programming and verification are shown in
Table 2-3.
Depending on the 4-bit command, the 16-bit operand
represents 16 bits of input data, or 8 bits of input data
and 8 bits of output data.
Throughout this specification, commands and data are
presented as illustrated in Table 2-4. The 4-bit
command is shown MSb first. The command operand,
or “Data Payload”, is shown <MSB><LSB>. Figure 2-9
demonstrates how to serially present a 20-bit
command/operand to the device.
2.6.2
The core instruction passes a 16-bit instruction to the
CPU core for execution. This is needed to setup
registers as appropriate for use with other commands.
