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. Use it with EVDD0 ≥ Vb.
2. Set the fMCK value to keep the hold time of SCLr = "L" and SCLr = "H".
Caution Select the TTL input buffer and the N-ch open drain output (V
DD tolerance) mode for the SDAr pin and
the N-ch open drain output (VDD tolerance) mode for the SCLr pin by using port input mode register g
(PIMg) and port output mode register g (POMg).
