NOTES:
1) DURING THE FIRST 8 CLOCKS CYCLES, THE MOSI PIN IS HIGH IMPEDANCE AND THE SPI MASTER DRIVES DATA ONTO THE MOSI PIN. SETUP AND HOLD TIMES ARE THE SAME AS
FOR FULL-DUPLEX MODE.
2) FOR SPI WRITE CYCLES, THE MOSI PIN CONTINUES TO BE HIGH IMPEDANCE AND THE EXTERNAL MASTER CONTINUES TO DRIVE MOSI.
3) FOR SPI READ CYCLES, AFTER THE 8TH CLOCK-RISING EDGE, THE MAX3420E STARTS DRIVING THE MOSI PIN AFTER TIME tON. THE EXTERNAL MASTER MUST TURN
OFF ITS DRIVER TO THE MOSI PIN BEFORE tON TO AVOID CONTENTION. PROPAGATION DELAYS ARE THE SAME AS FOR THE MOSI PIN IN FULL-DUPLEX MODE.
