Port P5 (P57 to P50)
Port P5 is an 8-bit input/output port. This port is switched between input and output modes using the P5 port input/
The P5 port contains bit wise programmable open-drain control. The P5 port open-drain control register (P5ODE)
If high frequency oscillation stops or becomes abnormal in NORMAL/IDLE mode, the TMP88FW45AFG generates
