W529XX Application Note
- 8 -
1. POWER ON INITIALIZATION
The W529XX will automatically execute the POI (Power On Initialization) process upon power up or depression
of the RESET pin. The voice group dedicated for POI is allocated at "64".
Upon power up, the W529XX resets itself to initial values by internally generating a POR (Power On Reset)
pulse to start the POI process.
During the POI process, certain triggers can override to take over if the EN register is set to properly enable
those triggers. Take the following example (for reference only); after the MODE1 & MODE2 registers are set to
their appropriate values according to the customers' configuration, the EN register is set to enable the falling-
edge triggers of TG1 and TG2. Therefore, during the reproduction of voice segments, like Voice1, Voice2,
Voice3, and Voice4, triggers TG1F and TG2F may terminate the normal operation of the POI process and start
a new trigger later on.
See also "Register definition and control" for default settings during a power up.
2. GROUP NUMBER ALLOCATION
For direct trigger inputs, there are 8 voice groups allocated to four TG pins: voice groups 0, 2, 4, and 6 are for
falling edge triggers, and voice groups 1, 3, 5, and 7 are used for the rising edge triggers.
