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
|
|
