eZ80L92 Module Product Specification
16
2.93 V. This reset pulse ensures that the board always starts in a defined condi-
tion. The RESET pin on the I/O connector reflects the status of the RESET line. It
is a bidirectional pin for resetting external peripheral components or for resetting
the eZ80L92 Module with a low-impedance output (e.g. a 100-Ohm pushbutton).
Serial Interface Ports
The processor contains two 16550-style UARTs with programmable baud rate
generators. UART0 is typically used for console I/O and initial boot code upload or
to connect remote peripherals that can be controlled and monitored via Ethernet.
UART0 is connected to GPIO PD[0:3] on the I/O connector. There are no RS232-
level shifters on the eZ80L92 Module.
Note: Do not connect an RS-232 interface without level shifters.
UART1 can be used for modem attachment or as a communications port to a host
computer, where the embedded Ethernet module emulates an AT-style modem for
internet access. UART1 does not offer onboard RS232-level shifters.
