Parameter 1 Most Significant bit

UART mode operating parameter values
ValueNameDescription
n MODE = DMX Most Significant bit of number of bytes to transmit between Start Code and automatic Break generation
n MODE = DALI Control Device Most Significant bit of Idle time delay after which a Forward Frame is sent. Measured in half-bit periods.
n MODE = DALI Control Gear Most Significant bit of delay between the end of a Forward Frame and the start of the Back Frame. Measured in half-bit periods.
