4.6.2.8. PIO as Parallel Output Interface  
Table 4–12: PIO output mode timing  
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.
