1. Notes
• The ARM has a 32 bit I/O register and 8 analogue
input lines
• On the E-blocks ARM board the 32 bit register
has been broken down into four ports - Ports A,
B, C and D. The pin to port allocation does not
correspond directly 0-31 with Ports A-D due to
the need to place serial communications pins
on the same port (Port C). Please refer to the
table on the left when working with the 32 bit
I/O register.
• Four of the analogue lines use pins in the 32 bit
digital I/O port. Four of the analogue lines are
separate only lists.
• Port E contains the 8 analogue input lines. This
means that Port E pins E0-E3 duplicate those of
Port D pins D0-D3. Pins E4-E7 are analogue lines
only, not general I/O.
• Pins B5 and D4 are used in USB communications.
Signals on these lines may affect the USB bus
causing erroneous activations of the USB
New device added wizard. To prevent this
either do not use Pins B5 and D4, or move the
Programming Pin Select jumper (J18) to the I/O
position whilst running the program (move it
back to USB for programming).
