Instruction set
STE2004S
Two different instructions formats are provided:
– With D/C set to LOW : commands are sent to the control circuitry.
– With D/C set to HIGH : the data RAM is addressed.
Two different instruction sets are embedded: the STE2001-like instruction set and the
extended instruction set. To select the STE2001-like instruction set, the EXT pad must be
connected to a logic LOW (connect to GND). To select the extended instruction set, the EXT
pad must be connected to a logic HIGH (connect to VDD1).
The instruction syntax is summarized in Table 8. (basic-set) and Table 9. (extended set).
