Note: P0, P1, … Represent the pixel/segment numbers on the LCD.
A charge pump suitable for driving VLCD is included on-chip. This circuit creates 5V from the 3.3V supply. A contrast DAC is
provided that permits the LCD full-scale voltage to be adjusted between VLCD and 70% of VLCD. The LCD_NUM register
defines the number of dual purpose pins used for LCD segment interface.
LCD Voltage Boost Circuitry
A voltage boost circuit may be used to generate 5V from the 3.3V supply to support low-power 5V devices, such as LCDs.
Figure 10 shows a block diagram of the voltage boost circuitry including the voltage regulators for V2P5 and V2P5NV. When
activated using the I/O RAM register LCD_BSTEN (0x2020[7]), the boost circuitry provides an AC voltage at the VDRV output
pin (see the Applications section for details).

UART (UART0) and Optical Port (UART1)
The 71M6511/6511H includes an interface to implement an IR or optical port. The pin OPT_TX is designed to directly drive an
external LED for transmitting data on an optical link (low-active). The pin OPT_RX, also low-active, is designed to sense the
input from an external photo detector used as the receiver for the optical link. These two pins are connected to a dedicated
UART port. OPT_TX can be tristated if it is desired to multiplex another I/O pin to the OPT_TX output. The control bit for the
OPT_TX output is the I/O RAM register OPT_TXDIS (0x2008[5]).
