PIC16F88X
3.2.6.5
After receiving this command, the chip will transmit
data bits out of the data memory starting with the
second rising edge of the clock input. The ICSPDAT pin
will go into Output mode on the second rising edge, and
it will revert to Input mode (high-impedance) after the
16th rising edge. As previously stated, the data
memory is 8 bits wide, and therefore, only the first 8 bits
that are output are actual data. If the data memory is
code-protected, the data is read as all zeros. A timing
diagram of this command is shown in Figure 3-8.
FIGURE 3-8:
3.2.6.6
The PC is incremented when this command is
received. A timing diagram of this command is shown
in Figure 3-9.
It is not possible to decrement the address counter. To
reset this counter, the user should exit and re-enter
Program/Verify mode.
