NOTES: 1. I = in�ut� O = out�ut� P = �owe� su��y.

2. 5V-T = 5V to�e�ant.

3. HT��F1�51B does not inc�ude the VB�T� XT�L��KIN and XT�L��KOUT �ins.

4. The GPIOs a�e in �F0 state afte� VDD18 �owe� on �eset (POR) exce�t the RTCOUT �in of Backu�

Domain I/O. The RTCOUT �in is �eset by the Backu� Domain �owe�-on-�eset (PORB) o� Backu�

Domain softwa�e �eset (B�K_RST bit in B�K_CR �egiste�).

5. The backu� domain of I/O �ins has d�iving cu��ent ca�abi�ity �imitation (< 1m� @ VB�T = �.�V).
