Conventions, Abbreviations and Acronyms
This hardware manual describes the PCM-061 System on Module, also referred to as phyCORE-i.MX7. The manual
specifies the phyCORE-i.MX7's design and function. Precise specifications for the NXP i.MX7 microcontrollers can be found
in NXP's i.MX7 Data Sheet and Technical Reference Manual.
NOTE:
The BSP delivered with the phyCORE-i.MX7 usually includes drivers and/or software for controlling all components
such as interfaces, memory, etc.. Therefore programming close to hardware at register level is not necessary in most
cases. For this reason, this manual contains no detailed description of the controller's registers, or information relevant
for software development. Please refer to the i.MX7 Reference Manual if such information is required.
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), or that have a dash on top of
the signal name (e.g.: 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 MSB of the address byte. The correct
value of the LSB which depends on the desired command (read (1), or write (0)) must be added to get the complete
address byte. E.g. given address in this manual 0x41 => complete address byte = 0x83 to read from the device and
0x82 to write to the device.
•
Tables which describe jumper settings show the default position in
bold text
•
Text in blue italic indicates a hyperlink within, or external to the document. Click these links to quickly jump to the

•
References made to the phyCORE-Connector always refer to the high density Samtec connectors on the
undersides of the phyCORE-i.MX7
