READ DATA FROM DATA MEMORY
The Read Data from Data Memory command 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. 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 4-5.

INCREMENT ADDRESS
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 7FFFh, it
will wrap-around to location 0000h. If the address is
incremented from FFFFh, it will wrap-around to location
8000h.
