Description
The ATSAM9707 is a highly integrated sound processor studio that combines a spe-
cialized high-performance RISC-based digital signal processor (synthesis/DSP) and a
general-purpose 16-bit CISC-based control processor on a single chip. An on-chip
memory management unit (MMU) allows the synthesis/DSP and the control processor
to share external ROM and/or RAM memory devices. An intelligent peripheral I/O
interface function handles other I/O interfaces, such as the ISA PC bus, the on-chip
MIDI UART and the codec control interface, with minimum intervention from the con-
trol processor.

bus directly (24 mA buffer).
Information on these pins is:
- parallel MIDI (MPU-401 type applications)
- Adlib control (game sound-type emulation)
- Down-/upload of PCM data or application programs
Direct ISA PC bus drive requires 5V V
