DIO Ports
The 71M6511/6511H includes up to 12 pins of general purpose digital I/O. These pins are dual function and can alternatively
be used as LCD drivers. Figure 8 shows a block diagram of the DIO section.
On reset or power-up, all DIO pins are inputs until they are configured for the desired direction. The pins are configured and
controlled by the DIO and DIO_DIR registers (SFRs) and by the five bits of the I/O register LCD_NUM (0x2020[4:0]). See the
description for LCD_NUM in the I/O RAM Section for a table listing the available segment pins versus DIO pins, depending on
the selection for LCD_NUM . Generally, increasing the value for LCD_NUM will configure an increasing number of general
purpose pins to be LCD segment pins, starting at the higher pin numbers.

Each pin declared as DIO can be configured independently as an input or output with the bits of the DIO_DIRn registers. Table
52 lists the direction registers and configurability associated with each group of DIO pins. Table 53 shows the configuration for
a DIO pin through its associated bit in its DIO_DIR register.
