6.5.7 MCU PINS
The MCU PINS tool provides a means of reading and setting the S32K144 input and output pins for signals
FS0B, INTB, RSTB, FCCUx, LVIOx:
• FS0B, INTB, RSTB are MCU inputs.
• FCCUx are MCU outputs.
• LVIOx can be configured as input or output for the MCU depending on the configuration on the FS2300
device.
Note: The configuration of LVIOx pins must be done by OTP. Depending on the chosen functionality for LVIOx
pins, the hardware must be configured as explained in
The MCU PINS panel consists of three sections:
• Log window: Maintains a running log of events initiated during the current session. A drop-down menu in the
upper left allows the log to be filtered by register read, register write, pin read, and pin write. Buttons in the
upper right allow the Log window contents to be saved, cleared, or run.
• I/Os Function Selection window: To use the MCU PINS tool, it is mandatory to select the FS23 I/Os
settings as configured in OTP/Mirror tabs in order to configure MCU pins accordingly. Without this information,
MCU pins cannot be configured properly.
• MCU Input Pins Reading window: To read or poll the listed MCU pins during a selected time duration.
• MCU Output Pins Setting window: To set the FCCUx and LVIOx (when configured as output) pins high or
low on MCU side.
