Synchronous Serial Interface (SSI)
ATAM862-4
SSI Features:
SSI Peripheral Configuration
The synchronous serial interface (SSI) can be used either for serial communication with external
devices such as EEPROMs, shift registers, display drivers, other microcontrollers, or as a
means for generating and capturing on-chip serial streams of data. External data communication
takes place via the Port 4 (BP4),a multi-functional port which can be software configured by writ-
ing the appropriate control word into the P4CR register. The SSI can be configured in any of the
following ways:
• With Timer 1
• With Timer 2
• With Timer 3
1. 2-wire external interface for bi-directional data communication with one data terminal
2. 3-wire external interface for simultaneous input and output of serial data, with a serial

and one shift clock. The SSI uses the Port BP43 as a bi-directional serial data line (SD)

input data terminal (SI), a serial output data terminal (SO) and a shift clock (SC). The
SSI uses BP40 as shift clock (SC), while the serial data input (SI) is applied to BP43
(configured in P4CR as input). Serial output data (SO) in this case is passed through to
BP42 (configured in P4CR to T2O) via the Timer 2 output stage (T2M2 configured in
mode 6).
of performing a variety of data modulation and demodulation functions (see section
Timer). The modulating data is converted by the SSI into a continuous serial stream of
data which is in turn modulated in one of the timer functional blocks. Serial demodu-
lated data can be serially captured in the SSI and read by the controller. In the Timer 3
modes 10 and 11 (demodulation modes) the SSI can only be used as demodulator.
