NRF9E5 Datasheet, PDF (62/104 Pages) List of Unclassifed Manufacturers – 433/868/915MHz RF Transceiver with Embedded 8051 Compatible Microcontroller and 4 Input, 10 Bit ADC

PRODUCT SPECIFICATION
nRF9 E5 Single Chip Transceiver with Embedded Microcontroller and ADC
18.3 Instruction Set
All nRF9E5 instructions are binary-code–compatible and perform the same functions
that they do in the industry standard 8051. The effects of these instructions on bits, flags,
and other status functions is identical to the industry-standard 8051. However, the timing
of the instructions is different, both in terms of number of clock cycles per instruction
cycle and timing within the instruction cycle.
Table 55 to Table 60 lists the nRF9E5 instruction set and the number of instruction
cycles required to complete each instruction.
