SIGNAL NAME [1] | PIN TYPE [2] | DESCRIPTION [3] | ZCZ PIN [4] |
---|---|---|---|
PORz | I | Device Power-On (PORz) cold reset | R2 |
SAFETY_ERRORn | OD | ESM Safety Error Signal | D4 |
WARMRSTn | IO | Warm Reset Request (Input) / Warm Reset Status (Output) | C3 |
The SAFETY_ERRORn signal is implemented on an LVCMOS voltage buffer pin can be configured to operate as open-drain outputs by configuring the ESM module to source a constant low output and toggle the output enable. The output buffer drives low when enabled and is high impedance when disabled.
The (I2C OD FS) are the only IO voltage buffers which are fail-safe. These are implemented for I2C0 pins only. Other IOs do not allow any potential greater than (VDD + 0.3V) to be applied. This means you cannot source any potential to these pins when power is off. All attached devices that can source a potential to these IOs must be powered from the same power supply that is sourcing the respective IO power rail.
