Conventions, Abbreviations and Acronyms
This hardware manual describes the PCM-065 System on Module, henceforth referred to as phyCORE-i.MX8X.
The manual specifies the phyCORE-i.MX8X's design and function. Precise specifications for the NXP
Semiconductor i.MX8X microprocessors can be found in the
i.MX8X Processor Reference Manual
We refrain from providing detailed part specific information within this manual which can be subject to changes.
This is due to the continuous maintenance of our products. Please read the section
within the Preface.
The BSP delivered with the phyCORE-i.MX8X includes drivers and/or software for controlling all components
such as interfaces, memory, etc. Therefore, programming close to the hardware (at the register level) is not
necessary in most cases. For this reason, this manual contains no detailed description of the processor's
registers, or information relevant for software development. Please refer to the
if such information is needed.
Conventions
The conventions used in this manual are as follows:
•
Signals that are preceded by an "n", "/", or “#”character (e.g.: nRD, /RD, or #RD), are designated as
active low signals. That is, their active state is when they are driven low, or are driving low.
•
A "0" indicates a logic zero or low-level signal, while a "1" represents a logic one or high-level signal.
•
The hex-numbers given for addresses of I
2
C devices always represent the 7 most-significant bits
(MSB) of the address byte. The correct value of the least-significant bit (LSB) will depend on the desired
command (read (1), or write (0)) and must be added to get the complete address byte. E.g. given the
address in this manual 0x41 => complete address byte = 0x83 to read from the device and 0x82 to write
to the device
