4.6.2.7. PIO as Parallel Input Interface:
Program Download Mode
Handshake for PIO input in Program Download
Mode is accomplished through the RTR, PCS, and
PI12..PI19 signal lines
(see Fig. 4–29). The PR line
should be set to low level.
The MAS 35x9F will drive RTR low as soon as it is
ready to receive a byte and RTR will stay low until one
byte has been written. Writing of a byte is performed
with a PCS pulse, driven by the microcontroller. The
MAS 35x9F reads data after the falling edge of PCS
and will finish the cycle by setting RTR to high level
after the rising edge of PCS. The next data transfer is
initialized by the MAS 35x9F by driving the RTR line.
