Peripheral Signal Multiplexing on I/O Lines
Table 8-1.
The SAM9G25 features 4 PIO Controllers, PIOA, PIOB, PIOC and PIOD, which multiplex the I/O
lines of the peripheral set.
Each PIO Controller controls 32 lines, 19 lines, 32 lines and 22 lines respectively for PIOA,
PIOB, PIOC and PIOD. Each line can be assigned to one of three peripheral functions, A, B or
C. Refer to
assignments.
