71M6543F/71M6543G Data Sheet
When not needed for UART1, OPT_TX can alternatively be configured as SEGDIO51. Configuration is
via the OPT_TXE[1:0] (I/O RAM 0x2456[3:2]) field and LCD_MAP[51] (I/O RAM 0x2405[0]) . The
OPT_TXE[1:0] field allows the MPU to select VPULSE, WPULSE, SEGDIO51 or the output of the pulse
modulator to be sourced onto the OPT_TX pin. Likewise, the OPT_RX pin can alternately be configured
as SEGDIO55, and its control is OPT_RXDIS (I/O RAM 0x2457[2]) and LCD_MAP[55] (I/O RAM 0x2405[4]) .

Bit Banged Optical UART (Third UART)
As shown in Figure 15 , the 71M6543 can also be configured to drive the optical UART with a DIO signal
in a bit banged configuration. When control bit OPT_BB ( I/O RAM 0x2022[0] ) is set, the optical port is
driven by DIO5 and the SEGDIO5 pin is driven by UART1_TX. This configuration is typically used when
the two dedicated UARTs must be connected to high speed clients and a slower optical UART is
permissible.

2.5.10 Digital I/O and LCD Segment Drivers
2.5.10.1 General Information
The 71M6543 combines most DIO pins with LCD segment drivers. Each SEG/DIO pin can be configured
as a DIO pin or as a segment driver pin (SEG).
On reset or power-up, all DIO pins are DIO inputs (except for SEGDIO0-15, see caution note below) until
they are configured as desired under MPU control. The pin function can be configured by the I/O RAM
