The following table describes the instruction set of the NM93C06. In the table A3A2A1A0
corresponds to one of the sixteen 16-bit registers.
All commands and data are shifted in/out on the rising edge of the SK clock. All
instructions are initiated by a low-to-high transition on CS followed by a low-to-high
transition on DI.
A detailed explanation of the NMC93C06 E
considerations can be found in the data sheet. A source listing of the software used to
interface the NM93C06 with the COP8SAx7 is provided below.
