3.5
The PGC pin is used as a clock input pin and the PGD
pin is used for entering command bits and data input/
output during serial operation. Commands and data are
transmitted on the rising edge of PGC, latched on the
falling edge of PGC, and are Least Significant bit (LSb)
first.
3.5.1
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, PGC is cycled four times. The
commands needed for programming and verification
are shown in Table 3-2.
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 3-3. The 4-bit
command, Most Signification bit (MSb), is shown first.
The command operand, or “Data Payload”, is shown
<MSB><LSB>. Figure 3-10 demonstrates how to
serially present a 20-bit command/operand to the
device.

3.5.2
The core instruction passes a 16-bit instruction to the
CPU core for execution. This is needed to set up
registers as appropriate for use with other commands.
