SDAR
Serial Data Port A Receive.
Serial data is received on this pin at
standard TTL or CMOS level. An integrated
pull-up circuit enables connection of an
open-drain/open collector driver without an
external pull-up resistor. SDAR is used only
if IOM-1 mode is selected.

External
Awake
(terminal
specific
function). If a falling edge on this input is
detected, the ISAC-S generates an
interrupt and, if enabled, a reset pulse.

Serial Data Port A Transmit, IOM-1 mode.
Transmit data is shifted out via this pin at
standard TTL or CMOS levels.
Serial Data Strobe 1, IOM-2 mode.
A programmable strobe signal, selecting
either one or two B- or IC-channels on IOM-
2 interface, is supplied via this line. After
reset, SDAX/SDS1 takes on its function
only after a write access to SPCR is made.
