FIGURE 2-7:
2.5
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.
2.5.1
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 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.

command/operand to the device.
Throughout this specification, commands and data are
presented as illustrated in Table 2-4. The 4-bit command
is shown Most Significant bit (MSb) first. The command
operand, or “Data Payload”, is shown <MSB><LSB>.
Figure 2-8 demonstrates how to serially present a 20-bit
2.5.2
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.
