B0 : TEST
This is a test flag for SII. Be sure to set this flag to “0” in use. If this flag is set to “1”, be sure to initialize to set “0”.
B1 : INT2AE, B2 : INT2ME, B3 : INT2FE
These bits are used to select the output mode for the
2
INT
pin. Table 10 shows how to select the mode. To use an
alarm 2 interrupt, set alarm interrupt mode, then access the INT2 register and the alarm expansion register 2.

B4 : 32kE, B5 : INT1AE, B6 : INT1ME, B7 : INT1FE
These bits are used to select the output mode for the
1
