    P2.26 —
    General purpose digital input/output pin.
    D26 —
    External memory data line 26.
    BOOT0 —
    While RESET is low, together with BOOT1 controls booting and
    internal operation. Internal pull-up ensures high state if pin is left
    unconnected.
    P2.27 —
    General purpose digital input/output pin.
    D27 —
    External memory data line 27.
    BOOT1 —
    While RESET is low, together with BOOT0 controls booting and
    internal operation. Internal pull-up ensures high state if pin is left
    unconnected.
    BOOT1:0 = 00 selects 8-bit memory on CS0 for boot.
    BOOT1:0 = 01 selects 16-bit memory on CS0 for boot.
    BOOT1:0 = 10 selects 32-bit memory on CS0 for boot.
    BOOT1:0 = 11 selects internal flash memory.
    P2.28 —
    General purpose digital input/output pin.
    D28 —
    External memory data line 28.
    P2.29 —
    General purpose digital input/output pin.
    D29 —
    External memory data line 29.
    P2.30 —
    General purpose digital input/output pin.
    D30 —
    External memory data line 30.
    AIN4 —
    ADC, input 4. This analog input is always connected to its pin.
    P2.31 —
    General purpose digital input/output pin.
    D31 —
    External memory data line 31.
    AIN5 —
    ADC, input 5. This analog input is always connected to its pin.
    Port 3 —
    Port 3 is a 32-bit bidirectional I/O port with individual direction
    controls for each bit. The operation of port 3 pins depends upon the pin
    function selected via the Pin Connect Block.
