The SAA7130HL offers a peripheral interface with General Purpose Input/Output (GPIO) pins. Dedicated
functions can be selected:
a) Digital Video Port (VP): output only; in 8-bit and 16-bit formats, such as VMI, DMSD ( ITU-R BT.601 );
b) Transport Stream (TS) capture input: from the peripheral DTV/DVB channel decoder; synchronized by
c) Digitized raw DTV/DVB samples stream output: from internal ADCs; to feed the peripheral DTV/DVB
d) GPIO: as default (no other function selected); static (no clock); read and write from or to individually
e) Use an external pull-up resistor of 4.7 k at GPIO16 for an external 24.576 MHz crystal; due to an
f) Peripheral interrupt (INT) input: enabled by interrupt enable register; routed to PCI interrupt (INT_A).
