8.4.2 Serial Peripheral Interface (SPI) Mode

If MODE_SEL = F or H, the LMH1219 is in SPI mode. In SPI mode, the following pins are used for SPI bus communication:

  • MOSI (pin 10): Master Output Slave Input
  • MISO (pin 20): Master Input Slave Output
  • SS_N (pin 7): Slave Select (active low)
  • SCK (pin 21): Serial clock (input to the LMH1219 slave device)
