4.3.3
The Load Data for Data Memory command will load a
14-bit “data word” when 16 cycles are applied.
However, the data memory is only 8 bits wide and thus,
only the first 8 bits of data after the Start bit will be
programmed into the data memory. It is still necessary
to cycle the clock the full 16 cycles in order to allow the
internal circuitry to reset properly (see
FIGURE 4-3:
4.3.4
The Read Data from Program Memory command will
transmit data bits out of the program memory map
currently accessed, starting with the second rising edge
of the clock input. The ICSPDAT pin will go into Output
mode on the first falling clock edge, and it will revert to
Input mode (high-impedance) after the 16th falling edge
of the clock. If the program memory is code-protected
(CP), the data will be read as zeros (see
