A single device can play the role of Master or Slave, or a single device can be a Slave only.
A Master or Slave device has the ability to suspend data transfers if the device needs more
time to transmit or receive data.
Each I2C interface on the STR91xFA has the following features:
●
●
●
●
SSP interfaces (SPI, SSI, and MICROWIRE) with DMA
The STR91xFA supports two independent Synchronous Serial Port (SSP) interfaces,
designated SSP0, and SSP1. Primary use of each interface is for supporting the industry
standard Serial Peripheral Interface (SPI) protocol, but also supporting the similar
Synchronous Serial Interface (SSI) and MICROWIRE communication protocols.
SPI is a three or four wire synchronous serial communication channel, capable of full-duplex
operation. In three-wire configuration, there is a clock signal, and two data signals (one data
signal from Master to Slave, the other from Slave to Master). In four-wire configuration, an
additional Slave Select signal is output from Master and received by Slave.
The SPI clock signal is a gated clock generated from the Master and regulates the flow of
data bits. The Master may transmit at a variety of baud rates, up to 24 MHz
In multi-Slave operation, no more than one Slave device can transmit data at any given time.
Slave selection is accomplished when a Slave’s “Slave Select” input is permanently
grounded or asserted active-low by a Master device. Slave devices that are not selected do
not interfere with SPI activities. Slave devices ignore the clock signals and keep their data
output pins in high-impedance state when not selected. The STR91xFA supports SPI multi-
Master operation because it provides collision detection.
Each SSP interface on the STR91xFA has the following features:
