Bit 8 – P1[8] Parameter 1 Most Significant bit

UART mode operating parameter values

Value	Name	Description
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.
x	All other modes/Limited featured UART	Not used

UART mode operating parameter values

Value	Name	Description
n	MODE = DMX	Least Significant bits of number of bytes to transmit between Start Code and automatic Break generation
n	MODE = DALI Control Device	Least Significant bits of Idle time delay after which a Forward Frame is sent. Measured in half-bit periods.
n	MODE = DALI Control Gear	Least Significant bits of delay between the end of a Forward Frame and the start of the Back Frame. Measured in half-bit periods.
n	MODE = LIN	PID to transmit (Only Least Significant six bits used)
n	MODE = Asynchronous Address	Address to transmit (9th transmit bit automatically set to ‘`1`’)
