4.6.2.8. PIO as Parallel Output Interface
Some downloadable software may use the PIO inter-
face (lines PI19...PI12) as output. The data transfer
rate and conditions are defines by the software func-
tion.
Handshaking for PIO output mode is accomplished
through the RTW, PCS, and PI12..PI19 signal lines
(see Fig. 4–30). The PR line has to be set to high level.
RTW will go low as soon as a byte is available in the
output buffer and will stay low until a byte has been
read. Reading of a byte is performed with a PCS
pulse. Data is latched out from the MAS on the falling
edge of PCS and removed from the bus on the rising
edge of PCS.
