SAM3S Preliminary
SAM3S Preliminary
Note that multiplexing of peripheral lines A, B, C and D only affects the output line. The periph-
eral input lines are always connected to the pin input.
After reset, PIO_ABCDSR1 and PIO_ABCDSR2 are 0, thus indicating that all the PIO lines are
configured on peripheral A. However, peripheral A generally does not drive the pin as the PIO
Controller resets in I/O line mode.
Writing in PIO_ABCDSR1 and PIO_ABCDSR2 manages the multiplexing regardless of the con-
figuration of the pin. However, assignment of a pin to a peripheral function requires a write in the
peripheral selection registers (PIO_ABCDSR1 and PIO_ABCDSR2) in addition to a write in
PIO_PDR.
• the corresponding bit at level 1 in PIO_ABCDSR1 and the corresponding bit at level 1 in
PIO_ABCDSR2 means peripheral D is selected.
