The PCM code definition
The HT36A0 can only solve the voice format of the
signed 8-bit raw PCM. And the MCU will take the voice
code 80H as the end code.
So each PCM code section must be ended with the end
code 80H.
D/A Converter Interface
HT36A0 provides the IIS serial data format to support the
multiple D/A converters, one bit clock output and a word
clock signal for left/right stereo serial data transmission.
Clock Signal
The bit clock output signals DCK are used to synchronize
the IIS serial data.
The word clock signal LOAD divides the serial data into
left channel and right channel data for two-way audio out-
put.
LOAD
The word clock signal LOAD is used for IIS serial data.
The stereo serial data consists of 16-channel sound
generator.
On IIS format, a H state on LOAD is used for the
right channel, and a L state is used for the left
channel.
DCK
DCK bit clock is the clock source for the signal.
Stereo Serial Data Format
The audio output data is in serial mode with 16 bit digi-
tal signal and LSB first output. There is a high sam-
pling rate of 50kHz when the system clock is 12.8MHz
and with two channel outputs for Right/Left channel.
HT36A0 provides only one serial data format as IIS
mode. The user could directly connect a D/Aconverter
which can accept the IIS serial data format, like
HT82V731.
