Preliminary data
Description
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 16-bit memory on CS0 for boot.
D28 — External memory data line 28.
D29 — External memory data line 29.
D30 — External memory data line 30.
AIN4 — A/D converter, input 4. This analog input is always connected to its
pin.
D31 — External memory data line 31.
AIN5 — A/D converter, input 5. This analog input is always connected to its
pin.
Port 3 — Port 3 is a 32-bit bi-directional 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.
A0 — External memory address line 0.
A1 — External memory address line 1.
A2 — External memory address line 2.
A3 — External memory address line 3.
