4.2.3
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
FIGURE 4-3:
4.2.4
The address is incremented when this command is
received. It is not possible to decrement the address.
To reset this counter, the user must use the Reset
Address command or exit Program/Verify mode and re-
enter it.
If the address is incremented from address 1FFFh, it
will wrap-around to location 0000h. If the address is
incremented from 3FFFh, it will wrap-around to location
2000h.
