Hi Wang-san,
When SPIENA is enabled, tC2TDELAY is out of the range specified in the data sheet.
When checking "Wait for enable" as below, tC2TDELAY can not be within the range defined by DS.
When "Wait for enable" is not checked, tC2TDELAY falls within the range specified by DS.
Why is this? When checking A, does not this rule apply?
Best regards,
Sasaki
