PEF 81902
Functional Description
â
of a serial access to the registers. The T-SMINT
IX latches incoming data at the rising
edge of SCLK and shifts out at the falling edge of SCLK. Each access must be
terminated by a rising edge of CS. Data is transferred in groups of 8 bits with the MSB
first.
Pad mode of SDX can be selected ’open drain’ or ’push-pull’ by programming
MODE2.PPSDX.
Figure 6
shows the timing of a one byte read/write access via the serial control interface.
