Function
Data Clock: Clock of frequency equal to twice the
data rate on the IOM-interface
LT-S/LT-T: clock input
TE: clock output
NT: clock input
Address Bit 0 (Non-multiplexed bus type).
Address Bit 1 (Non-multiplexed bus type).
Address Bit 2 (Non-multiplexed bus type).
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.
Address Bit 3 (Non-multiplexed bus type).
Address Bit 4 (Non-multiplexed bus type).
Address Bit 5 (Non-multiplexed bus type).
SLD Interface Port, IOM-1 mode. This line
transmits and receives serial data at
standard TTL or CMOS levels.
External
function). If a falling edge on this input is
detected,
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.
