The CLOCK terminal on the PCI1520 can be an input or an output. The PCI1520 defaults the CLOCK terminal as
an input to control the serial interface and the internal state machine. Bit 27 (P2CCLK) in the system control register
(offset 80h, see Section 4.29) can be set by the platform BIOS or the serial EEPROM to enable the PCI1520 to
generate and drive CLOCK internally from the PCI clock. When the system design implements CLOCK as an output
from the PCI1520, an external pulldown resistor is required.

Zoomed Video Support
The PCI1520 allows for the implementation of zoomed video (ZV) for PC Cards. Zoomed video is supported by setting
bit 6 (ZVENABLE) in the card control register (PCI offset 91h, see Section 4.32) on a per-socket function basis.
Setting this bit puts 16-bit PC Card address lines A25
A4 of the PC Card interface in the high-impedance state. These
lines can then transfer video and audio data directly to the appropriate controller. Card address lines A3
A0 can still
access PC Card CIS registers for PC Card configuration. Figure 3
4 illustrates a PCI1520 ZV implementation.
