Figure 1. Serial Data Input Timing Diagram There are several other considerations for writing on the SPI:
- The R/W bit must be set to 0.
- The signal on the SDI pin is clocked into a shift register on each rising edge of the SCK pin.
- The CSB must be held low for data to be clocked. Device ignores clock pulses if CSB is held high.
- The CSB transition from high to low must occur when SCK is low.
- When SCK and SDI lines are shared between devices, TI recommends holding the CSB line high on any devices besides the intended programming target.
Figure 2. Serial Data Readback Timing Diagram There are several other considerations for SPI readback:
- The R/W bit must be set to 1.
- The MUXOUT pin is always for the address portion of the transaction.
- The address on the SDI pin is clocked into a shift register on each rising edge of the SCK pin.
- The data portion of the transaction on the SDI line is always ignored.
- The data on the MUXOUT pin should be considered valid on each rising edge of the SCK pin, provided all timing requirements are met.
- All CSB considerations for SPI writing also apply to SPI readback.
