Port mode
2.4.4 Port group 0
Note
The pin function after reset depends on the reset source, that means on bit OCDM.OCDM0. Re-
fer to “OCDM - On-chip debug mode register“ on page 45 and to the “On-Chip Debug Unit“ on
page 877.
• Port group 0 is an 8-bit port group. In alternative mode, it comprises pins for
• External interrupt (INTP0 to INTP6)
• Non-maskable interrupt (NMI)
• N-Wire debug interface reset (DRST)
• Output state of internal Voltage Comparator 0 (VCMPO0)
Port group 0 includes the following pins:

the following functions:
The setting of bit OCDM.OCDM0 applies only to pins of port type R.
For configuring P00 as NMI and/or INTP0 refer also to “Edge and Level
Detection Configuration“ on page 218.
