INT2 pin output
(2) Output of user-set frequency
INT1 pin or
The INT1 and INT2 registers are 1-byte data registers 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. SC2 to SC4 in the INT1 register,
and SC5 to SC7 in the INT2 register are 3-bit SRAM type registers that can be freely set by users.
