HD404818 Datasheet, PDF (42/100 Pages) Hitachi Semiconductor – 16-digit LCD driver

HD404818 Series
Input/Output
The MCU provides 26 I/O pins and 4 input-only pins including 10 high-current pins (15 mA max.).
Twenty-six I/O pins contain programmable pull-up MOS. When each I/O pin is used as an input, the data
control register (DCR) controls the output buffer. Table 19 shows the I/O pin circuit types.
The configuration of the I/O buffers is shown in table 19.
