ZHCSES1B March 2016 – October 2018 ADS1282-SP
PRODUCTION DATA.
The serial clock (SCLK) is an input that is used to clock data into (DIN) and out of (DOUT) the ADS1282-SP. This input is a Schmitt-trigger input that has a high degree of noise immunity. However, TI recommends keeping SCLK as clean as possible to prevent possible glitches from inadvertently shifting the data.
Data are shifted into DIN on the rising edge of SCLK and data are shifted out of DOUT on the falling edge of SCLK. If SCLK is held low for 64 DRDY cycles, data transfer or commands in progress terminate and the SPI interface resets. The next SCLK pulse starts a new communication cycle. This time-out feature can be used to recover the interface when a transmission is interrupted or SCLK inadvertently glitches. SCLK should remain low when not active.
