General Purpose I/O Registers
AT90CAN32/64/128
General Purpose I/O Register 0 – GPIOR0
General Purpose I/O Register 1 – GPIOR1
General Purpose I/O Register 2 – GPIOR2
The AT90CAN32/64/128 contains three General Purpose I/O Registers. These registers can be
used for storing any information, and they are particularly useful for storing global variables and
status flags.
The General Purpose I/O Register 0, within the address range 0x00 - 0x1F, is directly bit-acces-
sible using the SBI, CBI, SBIS, and SBIC instructions.
