b.) ONEKEY sequential play with ‘RESET’ enabled, the maximum ONEKEY play group is optioned
to be 5:
playing sequence: group1, group2, group12, group1, group2, group3, group4, group5, group1,
group2, ...
(the playing sequence is reset to group 1 after TR12 is accepted).
c.) ONEKEY random play, the maximum ONEKEY play group is optioned to be 6:
playing sequence: group4, group1, group6, group2, group3, ...
(trigger group lager than 6 will never appear).
C. Debouncing circuit
To prevent possible unwanted trigger caused from bouncing pulses or noise, any bouncing pulse shorter
than 20ms is ignored by the debouncing circuit. User should be awared that sufficient trigger pulse width
should be applied on trigger inputs when interfacing EM22300 to microprocessors.
III. Control output signals
EM22300 series offers several configurable control output signals for external control:
Device
Number of control outputs
4
Symbol
EM22309,EM22312,EM22316
EM22321,EM22330,EM22342,EM22360
SAF1, SAF2,
SAF3, SAF4
There are three output functions for each control output pin optional by mask optin. These functions are
defined as followed:
Output type
STOP
ACT
FLASH
Description
Output a 40ms active pulse as soon as section playing is stop
Output a steady active pulse while voice section is playing
Output flash pulses while voice section is playing
Whether an SAF pin issues control output signal or not is defined section by section in coding procedure.
If the issue of an SAF pin is enabled by a section, it will send out control output signal according to the
option of output function (STOP, ACT or FLASH).
For example, the output function of SAF pins are set to be:
SAF1 : STOP
SAF2 : FLASH
SAF3 : FLASH
SAF4 : ACT
The option of control output signal corresponds to the sections in group m is:
