Figure A-6 SPI Master Timing (CPHA =1)
Table A-18 SPI Master Mode Timing Characteristics1
NOTES:
1. The numbers 7, 8 in the column labeled “Num” are missing. This has been done on purpose to be consistent between the
Master and the Slave timing shown in Table A-19.
Conditions are shown in Table A-4 unless otherwise noted, CLOAD = 200pF on all outputs
