Status register 2 is a 1-byte register that is used to display and set various modes. The bit configuration is shown below.
*1. Don’t care (Both of 0 and 1 are acceptable).
*1. Don’t care (Both of 0 and 1 are acceptable).
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”.
These bits are used to select the output mode for the
alarm 2 interrupt, set alarm interrupt mode, then access the INT2 register.
These bits are used to select the output mode for the
alarm 1 interrupt, access the INT1 register after setting the alarm interrupt mode.
