DESCRIPTION OF FUNCTIONS
Selection of Control Mode
The MSM9800 series control mode or ML22300 series control mode is selected by setting the SEQEN pin. When
SEQEN = 1, the MSM9800 series control mode is selected.
When selecting the ML22300 series control mode, place the SEQEN pin at any level other than a “L” level.

Initial Setting
Set the noise elimination time, AOUT output rise/fall time, shift-to-standby time, EVIN0-5 activation pins,
EVIN0-5 pins, SEQ0-7 output sates, SEQ0-7 pins, SEQRST pin signal, and SEQRST pin by using ROM option.
Read ROM option data during initialization after powered on and perform each of the above settings.
Event Activation
Power-down is released by the change in the input signal to the EVIN0 pin or the activation pin set by ROM option,
and the address specified by the EVIN0-5 pins in time tCHT is internally captured and the event execution
according to the address is started.
Power-down is released on the rising or falling edge of the input signal to the EVIN0 pin or the activation pin set by
ROM option. By changes in the input signals other than the rising or falling edge of the input signal, power-down
is not released.
