Pin Function (5/5)
The teletext clock and data inputs are shared PIO pins, as shown in Table 15 .
High speed data port pins have a dual function, and can be used either to interface to an external IEEE 1394 link layer
controller or provide an IEEE 1284 parallel port interface.
PIO pins and alternative functions
To improve flexibility and to allow the STi5512 to fit into different set-top box application architectures, the input and
output signals from some of the peripherals are not directly connected to the pins of the device. Instead they are
assigned to the alternative function inputs and outputs of a PIO port bit. This scheme allows these pins to be configured
as general purpose PIO if the associated peripheral input or output is not required in that particular application.

Table 14 TAP pins
Table 17 shows the assignment of the alternative functions to the PIO bits. Parentheses ( ) in the table indicate
suggested or possible pin usages as a PIO, not an alternative function connection.
