INT pin output
(2) Output of user-set frequency
The INT register 1 is a 1-byte data register to set up the output frequency. Setting each bit B7 to B3 in the register to
“1”, the frequency which corresponds to the bit is output in the AND-form. SC4 to SC6 is 3-bit SRAM type registers
that can be freely set by users.
Example: B7 to B3 = 50h
16 Hz
8 Hz
4 Hz
