Pin Functions
Note: This module is designed so that it can be used with 4-bit and 8-bit microprocessors. In 4-bit mode data is transferred in two 4-bit cycles, and in 8-bit
mode data is transferred in one 8-bit cycle.
Supply conditions when the built-in reset circuit is used.
If the above conditions are not met the internal reset circuit may not function correctly. Therefore, instruction reset
should be used in such cases.
