GND pins The following I/O pins provide GND potential:
GND of the DS1104 is internally connected to PC ground.
Slave DSP Serial Peripheral Interface (SPI)
• TTL voltage range
• Output current range: ±13 mA
• SSOMI: SPI slave out, master in
• SSIMO: SPI slave in, master out
• SSTE: SPI slave transmit enable
• SSCLK: SPI clock
• I/O circuit and further electrical characteristics: see Slave DSP Digital I/O on page 142
