Section 9 I/O Ports
9.2.4
The relationship between register setting values and pin functions are as follows in each operating
mode. In the tables, the symbol “—” stands for Don't care.
Extended Mode:
The function of port 2 pins is switched as shown below according to the combination of the
CS256E and IOSE bits in SYSCR, the ADFULLE and CPCSE bits in BCR2 of BSC, and the
P2nDDR bit.
Addresses 13 and 11 in the following table are expressed by the following logical expressions:
