Value applies to VBAT_ANA1, VBAT_ANA2, VBAT_DIG1, and VBAT_DIG2 pins.

2

Must remain powered (even if the associated function is not used).

Applies to the output and bidirectional pins: P0_00 to P0_15, P1_00 to P1_15, P2_00 to P2_15, and P3_00 to P3_03.

4

Applies to the SYS_HWRST input pin with pull-up.

5

Applies to the three-state pins: P0_00 to P0_05, P0_08 to P0_15, P1_00 to P1_15, P2_00 to P2_15, P3_00 to P3_03.

6

Applies to the three-state pins with pull-ups: P0_00 to P0_05, P0_07 to P0_15, P1_00 to P1_15, P2_00 to P2_15, and P3_00 to P3_03.

7

Applies to the P0_06 three-state pin with pull-down.
