KB22688 TV SOUND MPS FOR TWO CARRIER SYSTEM
2nd bype : 10th ~ 17th bit ---- SUB address ( function )
3rd bype : 19th ~ 26th bit ---- DATA ( D1 ~ D8 )
Data transmitted to the KB22688 starts with the module address as follows:
b) Protocol of normal u-COM control ( PIN 22: STROBE )
1st Byte : 1 ~ 7th bit ---- chip select code ( 1000010B )
8th bit ---- NOT USE ( don’ t care )
2nd Bype : 9th ~ 16th bit ---- function assignment
3rd Bype : 17th ~ 24th bit ---- DATA ( D1 ~ D8 )
The module address of KB22688 in normal u-COM control mode is as follows.
The maximum STROBE pulse width in normal u-COM control mode should be under 6.0 mSEC. If the
STROBE pulse width excess the limit, KB22688 will be changed to DC control mode.
c) Control item in each control mode
In each control mode, control items is limited as follows.
*** DEFINITIONS ***
* PRE-SET : When power is ON, u-COM initials the status of KB22688 to pre-set status. ( All IC has
same pre-set status data )
* PRE-ADJUST SET : When power is ON, u-COM initials the status of KB22688 to pre-measured and
stored status. ( Different each IC )
* DATA TRANSMISSION : Transmit stored data to u-COM when u-COM requests.
* RECEIVE ACKNOWLEDGE : Return Acknowledge signal to u-COM after DATA receipt.
