13.3 - XTIMER Peripheral (trigger for ADC
channel injection)
This new peripheral is dedicated for the Channel
Injection Mode of the A/D converter. This mode
injects a channel into a running sequence without
disturbing this sequence. The peripheral event
controller stores the conversion results in memory
without entering and exiting interrupt routines for
each data transfer.
A channel injection can be triggered by an event
on Capture/Compare CC31 (Port P7.7) of the
CAPCOM2 unit.
The dedicated output XADCINJ of the XTIMER
must be connected externally on the input P7.7/
CC31.
Due to the multiplexed inputs, at a time, the ADC
exclusively converts the Port5 inputs or the
XPort10 inputs. If one "y" channel has to be used
continuously in injection mode, it must be exter-
nally hardware connected to the Port5.y and
XPort10.y inputs.
The XTIMER peripheral is enabled by setting
XPEN bit 2 of the SYSCON register and bit 3 of
the new XPERCON register.
