As mentioned in the P1022RM, the configuration pins are multiplexed with some of the bidirectional pins.
In case one of interfaces connected to these pins needs a pull up resistor, for instance (WE# of the NAND Flash (LFALE)) and I need to input a 0 to the config pin of the processor for a particular configuration, how can I achieve this (without an FPGA or a CPLD) as I cannot connect a pull up and a pull down on the same pin/connection.
