(4) INT register 1 access and INT register 2 access
In Read/Write the INT register 1, data varies depending on the setting of the status register 2. Be sure to Read/Write
the INT register 1 after setting the status register 2. When setting the alarm by using the status register 2, these
registers work as 3-byte alarm time data registers, in other statuses, they work as 1-byte registers. When outputting
the user-set frequency, they are the data registers to set up the frequency.
Read/Write the INT register 2 after setting INT2AE in the status register 2. When INT2AE is in “1”, the INT register 2
works as for setting the 3-byte alarm time data. The INT register 2 does not have the function to output the user-set
frequency. Regarding details of each data, refer to “4. INT register 1 and INT register 2” in “
Configuration of
Register
”.
Caution
Users cannot use both functions of alarm 1 interrupt and the output of user-set frequency
simultaneously.
