Notes:
1.
Corresponds to one bit width. RO output is nominally 9600 baud. If the
received baud rate exceeds 9600 baud, the receiver will adjust RO’s output
baud rate to prevent internal buffer overflow.
Inter-character gap on RO’s output is a function of the received character
rate and transmitted inter-character gap. Transmitted baud rates of less
than 9600 baud increases the inter-character gap on RO’s output.
Transmitted baud rates of greater than 9600 baud decreases the inter-
character gap on RO’s output.
