Note Use it with VDD ≥ Vb.
Caution Select the TTL input buffer for the SIp pin and the N-ch open drain output (VDD tolerance) mode for the SOp pin
and SCKp pin by using port input mode register g (PIMg) and port output mode register g (POMg). For V
IH and
V
IL, see the DC characteristics with TTL input buffer selected.
(Remarks are listed two pages after the next page.)
