(c) Transmission/reception completion interrupt request signals (INTCSI0, INTCSI1)
INTCSIn is set (1) upon completion of data transmission/reception.
Caution The delay mode (CSIT bit = 1) is valid only in the master mode (bits CKS2 to CKS0 of the
CSICn register are not 111B). The delay mode cannot be set when the slave mode is set
(bits CKS2 to CKS0 = 111B).

performed
