INPUT PROTECTION
All I/O pins on the Z8E001 have diode input protection.
There is a diode from the I/O pad to VCC and VSS (Figure
41).
However, on the Z8E001, the RESET pin has only the input
protection diode from pad to VSS (Figure 42).

Figure 42. RESET Pin Input Protection
The high-side input protection diode was removed on this
pin to allow the application of high voltage during the OTP
programming mode.
For better noise immunity in applications that are exposed
to system EMI, a clamping diode to VCC from this pin can
be required to prevent entering the OTP programming mode
or to prevent high voltage from damaging this pin.
