General Purpose I/O 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
Unused USB pins should be three-stated with the D+ line
pulled high through the internal pull-up resistor and the D– line
pulled low through the internal pull-down resistor.
Unused GPIO pins should be configured as outputs and 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
illustrates the interface for connecting a 16-bit ROM or 16-bit RAM to the EZ-Host external memory interface. In 16-bit
