TSADCC Pin Description
The TSADC controller is not continuously clocked. The programmer must first enable the
TSADC controller Clock in the Power Management Controller (PMC) before using the TSADC
controller. However, if the application does not require TSADC controller operations, the TSADC
controller clock can be stopped when not needed and be restarted later.
Configuring the TSADC controller does not require the TSADC controller clock to be enabled.
The TSADCC interrupt line is connected on one of the internal sources of the Advanced Inter-
rupt Controller. Using the TSADCC interrupt requires the AIC to be programmed first.
Table 40-2.
The analog input pins can be multiplexed with PIO lines. In this case, the assignment of the
TSADCC input is automatically done as soon as the corresponding channel is enabled by writing
the register TSADCC_CHER. By default, after reset, the PIO lines are configured as input with
its pull-up enabled and the TSADCC inputs are connected to the GND.
The pin TSADTRG may be shared with other peripheral functions through the PIO Controller. In
this case, the PIO Controller should be set accordingly to assign the pin TSADTRG to the
TSADCC function.
