8.1.1. Serial port configuration (UART0, UART1, UART2)
The serial ports have a different transmission capacity according to the programmed
mode:
• UART0 allows frames of up to 912 bytes in all cases
• UART1 allows frames of up to 912 bytes in transparent mode (configuration values
$88 to $8C), but only up to 48 bytes in the other modes.
• UART2 allows frames of up to 48 bytes, but up to 912 bytes when connected to he
Host. UART2 is a special port, only available at TTL levels (3.3V), intended for
connection to the BiomaxPlus-DB module, for Offline behaviour add-on.
The behaviour of the serial ports is defined from the $1A, $1B and $1C configuration
parameters:
Depending on the function associated to the port and baud rate, the values to be assigned
are detailed in the following table.
