Envelope type definition
The HT36A1 provides a function to easily program the
envelope by setting the data of ENV1~0 and A_R. It
forms a vibrato effect by a change of the volume to at-
tach and release alternately.
The A_R signalis used to define the volume changein
attach mode or release mode and ENV1~0 is used to
definewhichvolumecontrolbitwillbechangeable.On
the attach mode, the control bits will be sequentially
signaled down to 0. On the release mode, the control
bits will be sequentially signaled up to 1. The relation-
ship is shown in the following table.
The PCM code definition
The HT36A1 can only solve the voice format of the
signed8-bitrawPCM.AndtheMCUwilltakethevoice
code 80H as the end code.
So each PCM code section must be ended with the
end code 80H.
