Different types of host busses are supported:
The host interface type is set via the dedicated pins H_sel and sys_clk. The
SAA7893HL has a dedicated interrupt output pin.
The SAA7893HL supports three different front-end interfaces which are selectable
via the host interface:

Explanation of input and output ports:
IN: digital input port; all dedicated inputs are TTL tolerant.
IN1: digital input port with internal pull-up resistor.
I/O10: bidirectional port with 10 ns slew rate.
O10: 3-state (in test mode) output port with 10 ns slew rate.
APIO: analog input port.
VDDCO: analog V
VSSCO: analog V
GND_IO: ground for I/O pads.
VCC_IO: V
GND_core: ground for core.
VCC_core: V
