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).

Cautions 1. Select the TTL input buffer for the SIp pin and the N-ch open drain output (V
DD tolerance) mode for
the SOp pin and SCKp pin by using port input mode register g (PIMg) and port output mode register
g (POMg).
2. Use it with EV
DD0 ≥ Vb.

2. p: CSI number (p = 00, 01, 10, 20, 30, 31), m: Unit number , n: Channel number (mn = 00, 01, 02, 10,
12, 13), g: PIM and POM number (g = 0, 1, 4, 5, 8, 14)

4. CSI01 of 48-, 52-, 64-pin products, and CSI11 and CSI21 cannot communicate at different potential. Use
other CSI for communication at different potential.
