Description
Digital ground. All these pins should be returned to a ground plane
Core power. All these pins should be returned to nominal 1.8V or to
PWROUT if the built-in power switch is used.
Periphery power. All these pins should be returned to nominal 3.3V.
Power switch input; should be returned to nominal 1.8V even if the
power switch is not used
Power switch output; should be connected to all VC18 pins if the power
switch is used
Slave 8-bit interface data. Output if CS and RD are low (read from chip),
input if CS and WR are low (write to chip). Type of data defined by A0
input.
SmartMedia data or other peripheral data
General-purpose I/O; can be programmed individually as input or
output
Optional bit clocks for digital audio input. Used for sampling rate
conversion, for external incoming digital audio such as AES/BEU or
S/Pdif.
Optional word selects for digital audio input. Used for sampling rate
conversion, for external incoming digital audio such as AES/BEU or
S/Pdif.
Slave 8-bit interface address. Indicates data/status or data/ctrl transfer
type (CS/ RD low or CS/WR low)
SmartMedia presence detect
General-purpose input pin
Serial slave synchronous interface input clock
Slave 8-bit interface chip select, active low
General-purpose input pin
Serial slave synchronous interface input sync signal
Slave 8-bit interface write, active low. D7 - D0 data is sampled by chip
on WR rising edge if CS is low
SmartMedia configuration. This pin is sensed after power-up. If found
low, it is assumed that a SmartMedia connector is present. The built-in
firmware will wait for SmartMedia SMPD.
General-purpose input pin
