3.2.1
The serial control interface (SCI) is compatible to the SPI interface of Motorola or
Siemens C510 family of microcontrollers.
The SCI consists of 4 lines: SCL, SDX, SDR and CS. Data is transferred via the lines
SDR and SDX at the rate given by SCL. The falling edge of CS indicates the beginning
of a serial access to the registers. The IPAC-X latches incoming data at the rising edge
of SCL and shifts out at the falling edge of SCL. Each access must be terminated by a
rising edge of CS. Data is transferred in groups of 8 bits with the MSB first.
