PIC16F785/HV785
3.1.5.3
After receiving this command, the device will load in 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. The data memory
contains 256 bytes.
FIGURE 3-6:
3.1.5.4
After receiving this command, the device will transmit
data bits out of the program memory (user or
configuration) currently accessed, starting with the
second rising edge of the clock input. The data pin will
go into Output mode on the second rising clock edge,
and it will revert to Input mode (high-impedance) after
the 16th rising edge.
If the program memory is code-protected (CP = 0), the
data is read as ‘0’s.
