D.6 Programming Sheets
The worksheets shown on the following pages contain listings of major programmable registers for the
DSP56366. The programming sheets are grouped into the following order:
• Central Processor
• Host Interface (HDI08)
• Serial Host Interface (SHI)
• Two Enhanced Serial Audio Interfaces (ESAI and ESAI_1)
• Digital Audio Interface (DAX)
• Timer/Event Controller (TEC)
• GPIO (Ports B-E)
Each sheet provides room to write in the value of each bit and the hexadecimal value for each register.
Programmers can photocopy these sheets and reuse them for each application development project.
For details on the instruction set of the DSP56300 family chips, see the DSP56300 Family Manual.
