PIO[8:6] can be used to form a master I
Therefore, it is suited only to relatively slow functions such as driving a dot matrix liquid crystal display (LCD), keyboard
scanner or EEPROM.
Notes:
BC41B143A-ds-003Pc
PIO lines need to be pulled-up through 2.2kΩ resistors.
PIO[7:6] dual functions, UART bypass and EEPROM support, therefore, devices using an EEPROM cannot
support UART bypass mode.
For connection to EEPROMs, refer to CSR documentation on I
information on the type of devices currently supported.
