The ICSPCLK pin is used as a clock input and the
ICSPDAT pin is used for entering command bits and
data input/output during serial operation. To input a
command, ICSPCLK is cycled six times. Each
command bit is latched on the falling edge of the clock
with the LSb of the command being input first. The data
input onto the ICSPDAT pin is required to have a
minimum setup and hold time (see Table 6-1), with
respect to the falling edge of the clock. Commands that
have data associated with them (Read and Load) are
specified to have a minimum delay of T
the command and the data. After this delay, the clock
pin is cycled 16 times with the first cycle being a Start
bit and the last cycle being a Stop bit.
