Other Interfaces
SPI
The SPI interface is a generic serial interface with the following functions:
The SPI supports:
I2C
The STV0684 features a hardware I2C master interface and supports the following features:
Comparator for low battery detection
The comparator circuit compares the battery voltage with an external reference voltage and
generates a low_batt signal for the CPU core.
Support for multi-media and secure digital cards
Support for serial flash where the ST20-EWARP code can be located
Full duplex, three-wire synchronous transfers
Single master/slave operation selectable via firmware or hardware
Programmable clock polarity
End of transfer interrupt flag
Write collision flag
Busy flag indication
I2C protocol
Standard I2C mode (100 kHz) / fast I
Single master mode
Transmitter/receiver performance
7/10 bit addressing
DMA mode data transfer
Clock stretching
