... Five 8-bit PWM ports are used to vary picture levels. The LDTC applications demand powerful I/O capabilities. The Z86127 fulfills this with 27 I/O pins dedicated to input and output. These lines are grouped into four ports, and are configurable under software control to provide timing, status signals, parallel I/O and an address/data bus for interfacing to external memory ...
