6. I/O Port
The MCU provides 8 bi-directional I/O ports. The PORT data is put in register $08 - $09. The PORT control register ($1B - $1C)
controls the PORT as input or output. Each I/O port has an internal pull-high resistor, which is controlled by PPULL of $15 and
the data of the PORT, when the PORT is used as input.
Port I/O mapping address is shown as follows:

Program Notes:
The pump circuit frequency can be 4kHz, or 2kHz (Selected by code option). When using the small LCD panel, the user can
select 2kHz pump frequency to save power. When using the large LCD panel, the user can select 4kHz pump frequency to have
more power supply ability for LCD use. LCD duty and bias are selected by code option.
