Status register 2 is a 1-byte register that is used to display and set various modes. The bit configuration is shown below.
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”.
To use the alarm 2 function, access the INT register 2 after setting this flag enable. Disable when this flag is in “0”,
enable when this flag is in “1”.
These flags are SRAM type registers, they are 3 bits as a whole, can be freely set by users.
To use the alarm 1 function, access the INT register 1 after setting INTA1AE = “1”, INT1ME = “0”, and INT1FE = “0”.
In other settings than this, these flags are disable for setting the alarm time (free registers).
