Note 1: During processor mode, these ports are switched to function as extended external signal pins. During external extension
mode, only P41-P43 are switched to function as external bus interface pins. Other pins become input/output port pins
when reset, so that some of these pins, if needed, must be set to function as external bus interface pins.
Note 2: These are triple-function pins. Their desired output function must be selected using the peripheral output select register.
Note 3: These ports cannot be used for input/output port function. The SBI#, MOD0 and MOD1 pin input levels can be read from
these ports.
