Product data sheet
6.9.2 Propagate reset
6.9.3 GPIO
The PCI system reset and ACPI power management state D3 is propagated to peripheral
devices by the dedicated pin PROP_RST_N. This signal is switched to active LOW by
reset and D3, and is only switched HIGH under control of the device driver ‘by will’. The
intention is that peripheral devices will use signal PROP_RST_N as Chip-Enable (CE).
The peripheral devices should enter a low power consumption state if
pin PROP_RST_N = LOW, and reset into default setting at the rising edge.
The SAA7134HL offers a set of General Purpose Input/Output (GPIO) pins, to interface to
on-board peripheral circuits. These GPIOs are intended to take over dedicated functions:
Any GPIO pin that is not used for a dedicated function is available for direct read and write
access via the PCI-bus. Any GPIO pin can be selected individually as input or output
(masked write). By these means, very tailored interfacing to peripheral devices can be
created via the SAA7134HL capture driver running on Windows operating systems.
At system reset (PCI reset) all GPIO pins will be set to 3-state and input, and the logic
level present on the GPIO pins at that moment will be saved into a special ‘strap’ register.
All GPIO pins have an internal pull-down resistor (LOW-level), but can be strapped
externally with a 4.7 k resistor to the supply voltage (HIGH-level). The device driver can
investigate the strap register for information about the hardware configuration of a given
board.
Table 17:
In accordance with the Absolute Maximum Rating System (IEC 60134). All ground pins connected
together and grounded (0 V); all supply pins connected together.

Peripheral interrupt input: four GPIO pins of the SAA7134HL can be enabled to raise
an interrupt on the PCI-bus. By this means, peripheral devices can directly intercept
