Figure 4 illustrates the interface for connecting an 8-bit ROM or
8-bit RAM to the EZ-Host external memory interface. In 8-bit
mode, up to 512K bytes of external ROM or RAM are supported.
General Purpose IO Interface (GPIO)
EZ-Host has up to 32 GPIO signals available. Several other
optional interfaces use GPIO pins as well and may reduce the
overall number of available GPIOs.
GPIO Description
All Inputs are sampled asynchronously with state changes
occurring at a rate of up to two 48 MHz clock cycles. GPIO pins
are latched directly into registers, a single flip-flop.
Unused Pin Descriptions
Ensure to tristate unused USB pins with the D+ line pulled high
through the internal pull up resistor and the D– line pulled low
through the internal pull down resistor.
Configure unused GPIO pins as outputs so they are driven low.
UART Interface
EZ-Host has a built in UART interface. The UART interface
supports data rates from 900 to 115.2K baud. It can be used as
a development port or for other interface requirements. The
UART interface is exposed through GPIO pins.
UART Features
Supports baud rates of 900 to 115.2K
8-N-1
UART Pins.
I2C EEPROM Interface
EZ-Host provides a master-only I2C interface for external serial
EEPROMs. The serial EEPROM can be used to store application
specific code and data. Use the I2C interface for loading code out
of EEPROM, it is not a general I2C interface. The I2C EEPROM
interface is a BIOS implementation and is exposed through
GPIO pins. Refer to the BIOS documentation for additional
details on this interface.
I2C EEPROM Features
Supports EEPROMs up to 64 KB (512K bit)
Auto-detection of EEPROM size
I2C EEPROM Pins
Serial Peripheral Interface
EZ-Host provides a SPI interface for added connectivity. EZ-Host
may be configured as either an SPI master or SPI slave. The SPI
interface can be exposed through GPIO pins or the External
Memory port.
SPI Features
Master or slave mode operation
DMA block transfer and PIO byte transfer modes
Full duplex or half duplex data communication
8-byte receive FIFO and 8-byte transmit FIFO
Selectable master SPI clock rates from 250 kHz to 12 MHz
Selectable master SPI clock phase and polarity
Slave SPI signaling synchronization and filtering
Slave SPI clock rates up to 2 MHz
Maskable interrupts for block and byte transfer modes
Individual bit transfer for non-byte aligned serial communi-
cation in PIO mode
Programmable delay timing for the active/inactive master SPI
clock
Auto or manual control for master mode slave select signal
Complete access to internal memory
