===========
NXP S32K3XX
===========
The `S32K3XX series <https://www.nxp.com/products/processors-and-microcontrollers/s32-automotive-platform/s32k-general-purpose-mcus/s32k3-microcontrollers-for-general-purpose:S32K3>`_ is a family of automotive-grade general-purpose microcontrollers from NXP Semiconductors. The chips are based around single, dual (lock-step) or tripple Arm Cortex-M7 cores, running at clockspeeds up to 240 MHz.
Supported MCUs
==============
The following list includes MCUs from the S32K3XX series and indicates whether they are supported in NuttX:

FlexIO No
GPIO Yes
LPCMP No
LPI2C Yes I2C Master only
LPSPI Yes

========== ======= ==========================
ADC
---
12-Bit Successive Approximation (SAR) Analog-to-Digital Converter (ADC). No driver support (yet).
eDMA
----
Enhanced Direct Memory Access module. There is a driver that was copied from the S32K1XX and i.MX RT ports. Some modifications have been made to make it work with S32K3XX, but it is far from feature-complete.
eMIOS
-----
The Enhanced Modular IO Subsystem (eMIOS) is a flexible timer and I/O module for real-time control applications. Its channels can be used for (pulse) counters, PWM outputs, input period measurements, and more. There is no driver implementation available (yet).
EMAC
----
10/100/200 Mbit/s Ethernet MAC. Driver is available.
FlexCAN
-------
The S32K3XX family has up to 8x FlexCAN modules with CAN FD support. A SocketCAN-compatible driver is available.
FlexIO
------
A configurable module providing a range of functionality like emulation of a variety of serial/parallel communication protocols, flexible 16-bit timers or programmable logic blocks. No driver available.
GPIO
----
Pins can be configured using :c:func:`s32k3xx_pinconfig` function. Writing to pins is done by :c:func:`s32k3xx_gpiowrite` function and reading is done by :c:func:`s32k3xx_gpioread`.
LPCMP
---
Analog Comparator. No driver support (yet).
LPI2C
-----
Low-Power Inter-Integrated Circuit (I2C) module supporting an interface to an I2C bus as master and/or
as a slave. The lower-half of this driver is initialize by calling :c:func:`s32k3xx_i2cbus_initialize`.
LPSPI
-----
Low-Power Serial Peripheral Interface (SPI) module that supports an interface to an SPI bus as a master
and/or a slave. The lower-half of this driver is initialize by calling :c:func:`s32k3xx_lpspibus_initialize`.
LPUART
------
Low-Power Universal Asynchronous Receiver/Transmitter (UART) module. UART is initialized automatically during
MCU boot.
QSPI
----
QuadSPI memory interface for external serial flash devices. A basic driver is available.
RTC
---
Real-Time Clock module. A driver is not (yet) available.
SAI
---
Synchronous Audio Interface for digital audio over I2S (Inter-IC Sound). No driver implemented.
