This hardware manual describes the PCM-058 System on Module in the following referred
to as phyCORE
®
-i.MX 6. The manual specifies the phyCORE
®
-i.MX 6's design and function.
Precise specifications for the NXP® Semiconductor i.MX 6 microcontrollers can be found in
the enclosed microcontroller Data Sheet/User's Manual.
Note: We refrain from providing detailed part specific information within this manual,
which can be subject to continuous changes, due to part maintenance for our products.
Please read the paragraph "
Product Change Management and information in this
manual on parts populated on the SOM" within the Preface.
Note: The BSP delivered with the phyCORE
®
-i.MX 6 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.MX 6 Reference Manual , if such
information is needed to connect customer designed applications.
Conventions
The conventions used in this manual are as follows:
ƒ
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.
ƒ
A "0" indicates a logic zero or low-level signal, while a "1" represents a logic one or
high-level signal.
ƒ
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
ƒ
Tables which describe jumper settings show the default position in bold, blue text .

References made to the phyCORE-Connector always refer to the high density Samtec
connector on the undersides of the phyCORE-i.MX 6 System on Module.
