DIO Ports
The 71M6513/6513H includes up to 22 pins of general purpose digital I/O. 18 of 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.
