b. INT Register 1 and INT Register 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.
