Table 14 STi5512 TAP pins
4.1 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.
