7.6 MISRA Compliance Report
This section lists the compliance and deviations for MISRA standards of coding practice for the
QTouch acquisition method libraries for 2K devices
7.6.1
The QTouch acquisition method libraries for 2K devices adhere to the MISRA standards. The
additional reference code provided in the form of sample applications is not guaranteed to be
MISRA compliant.

7.6.3.1
The QTouch acquisition method libraries were subject to the above mentioned MISRA
compliance rules. The following exceptions have not been fixed as they are required for the
implementation of the library.

Rule Description
Rule states that all code
shall conform to ISO 9899
standard C, with no
extensions permitted.
Rule states that implicit
conversion from Underlying
long to unsigned long
This Rule says that a 'U'
suffix shall be applied to all
constants of 'unsigned' type
Rule states that go-to
statement should not be
For ATtiny 2K devices - touch_api_2kdevice.h, touch_qt_config_2kdevice.h and
qt_asm_tiny_mega_2kdevice.S
IAR Embedded Workbench
The MISRA C Compliance has been performed for the library
using MISRA C 2004 Rules in IAR Workbench development
environment.
MISRAC 2004 Rule Set
Exception noted / How it is addressed
This Rule is not supported as the library
implementation requires IAR extensions like
__interrupt. These intrinsic functions relate to
device hardware functionality, and cannot
practically be avoided.
The library uses macros to combine symbol
definitions to form a unique expanded symbol
name and in this, the usage of unsigned qualifiers
for numeric constants (e.g. 98u) causes name
mangling. This is the only occurrence of this error
in the library.

The library uses conditional jump instructions to
reduce the code footprint at a few locations and
