Notes 1. When DAP0n = 0 and CKP0n = 0, or DAP0n = 1 and CKP0n = 1. The SIp setup time becomes “to SCKp↓” and
SIp hold time becomes “from SCKp↓” when DAP0n = 0 and CKP0n = 1, or DAP0n = 1 and CKP0n = 0.
2. When DAP0n = 0 and CKP0n = 0, or DAP0n = 1 and CKP0n = 1. The delay time to SOp output becomes “from
SCKp↑” when DAP0n = 0 and CKP0n = 1, or DAP0n = 1 and CKP0n = 0.
3. C is the load capacitance of the SCKp and SOp output lines.
