Alternate Functions of Port F
Table 9-17.
Note:
The Port F has an alternate function as analog input for the ADC as shown in
some Port F pins are configured as outputs, it is essential that these do not switch when a con-
version is in progress. This might corrupt the result of the conversion. If the JTAG interface is
enabled, the pull-up resistors on pins PF7 (TDI), PF5 (TMS) and PF4 (TCK) will be activated
even if a reset occurs.
Table 9-18.
The alternate pin configuration is as follows:
• TDI, ADC7 – Port F, Bit 7
ADC7, Analog to Digital Converter, input channel 7
