EM73220 can recoder 63 different voice and one stop section . The section No. is controlled by P6 ( 1:0
) and P5 ( 3:0 ). The range of section number is 000000B~111110B (0~62). The section 63 is stop section which
truns off the D/A converter to disable speech synthesizer.
PROGRAM EXAMPLE: Enable speech synthesizer for section 2 for 6 K sample rate:
LDIA #0000B;
OUTA P9; set 6K sample rate
LDIA #0010B;
OUTA P5;
ANDA #1100B;
OUTA P6; enable speech synthesizer .;
Port 6 write
ACT
If this interrupt request are not accepted by CPU from
the falling edge to next P6 write, then CPU will not clear
this interrupt request, user must clear by program himself and
the stop section will generate an interrupt request, then must be
clear by user too.
