Caution The pins mounted depend on the product. Refer to 2.1.1 20-pin products to 2.1.14 128-pin products,
and 2.1.15 Pins for each product (pins other than port pins).

Notes 1. When DAPmn = 0 and CKPmn = 0, or DAPmn = 1 and CKPmn = 1. The SIp setup time becomes “to SCKp↓”
when DAPmn = 0 and CKPmn = 1, or DAPmn = 1 and CKPmn = 0.
2. When DAPmn = 0 and CKPmn = 0, or DAPmn = 1 and CKPmn = 1. The SIp hold time becomes “from SCKp↓”
when DAPmn = 0 and CKPmn = 1, or DAPmn = 1 and CKPmn = 0.
3. When DAPmn = 0 and CKPmn = 0, or DAPmn = 1 and CKPmn = 1. The delay time to SOp output becomes
“from SCKp↑” when DAPmn = 0 and CKPmn = 1, or DAPmn = 1 and CKPmn = 0.
4. C is the load capacitance of the SOp output lines.
5. Transfer rate in the SNOOZE mode : MAX. 1 Mbps
Caution Select the TTL input buffer for the SIp pin and SCKp pin and the normal output mode for the SOp pin by
using port input mode register g (PIMg) and port output mode register g (POMg).
