I2C instances may be implemented with dedicated, I2C compliant, open-drain I/O buffers, or with standard

LVCMOS I/O buffers. The I2C instances associated with open-drain I/O buffers can support Hs-mode (up to 3.4

Mbps when the I/O buffers are operating at 1.8 V but limited to 400 kbps when the I/O buffers are operating at

3.3 V).

The I2C instances associated with standard LVCMOS I/O buffers can support Fast-mode (up to 400 kbps). The

LVCMOS I/O buffers being used on these ports are connected such they emulate open-drain outputs. This

emulation is achieved by forcing a constant low output and disabling the output buffer to enter the Hi-Z state.

8.5.13 Modular Controller Area Network (MCAN)

The Controller Area Network (CAN) is a serial communications protocol which efficiently supports distributed

real-time control with a high level of security. CAN has high immunity to electrical interference and the ability

to self-diagnose and repair data errors. In a CAN network, many short messages are broadcast to the entire

network, which provides for data consistency in every node of the system.

The MCAN module supports both classic CAN and CAN FD (CAN with Flexible Data-Rate) specifications. CAN

FD feature allows high throughput and increased payload per data frame. The classic CAN and CAN FD devices

can coexist on the same network without any conflict.

For more information, see Modular Controller Area Network section in Peripherals chapter in the device TRM.

8.5.14 Multichannel Audio Serial Port (MCASP)

This section introduces the Multichannel Audio Serial Port (MCASP) module and describes its main functions

and connections in the device.

The MCASP functions as a general-purpose audio serial port are optimized to the requirements of various audio

applications. The MCASP module can operate in both transmit and receive modes. The MCASP is useful for

time-division multiplexed (TDM) stream, Inter-IC Sound (I2S) protocols reception and transmission as well as

for an inter-component digital audio interface transmission (DIT). The MCASP has the flexibility to gluelessly

connect to a Sony/Philips digital interface (S/PDIF) transmit physical layer component.

Although inter-component digital audio interface reception (DIR) mode (this is, S/PDIF stream receiving) is not

natively supported by the MCASP module, a specific TDM mode implementation for the MCASP receivers allows

an easy connection to external DIR components (for example, S/PDIF to I2S format converters).

For more information, see Multichannel Audio Serial Port section in Peripherals chapter in the device TRM.

8.5.15 Multichannel Serial Peripheral Interface (MCSPI)

The MCSPI module is a multichannel transmit/receive, controller/peripheral synchronous serial bus.

For more information, see Multichannel Serial Peripheral Interface section in Peripherals chapter in the device

TRM.

8.5.16 Multi-Media Card Secure Digital (MMCSD)

The MMCSD Host Controller provides an interface to eMMC 5.1 (embedded Multi-Media Card), SD 4.10 (Secure

Digital), and SDIO 4.0 (Secure Digital IO) devices. The MMCSD Host Controller deals with MMC/SD/SDIO

protocol at transmission level, data packing, adding cyclic redundancy checks (CRCs), start/end bit insertion,

and checking for syntactical correctness

For more information, see Multi-Media Card Secure Digital section in Peripherals chapter in the device TRM.

8.5.17 Octal Serial Peripheral Interface (OSPI)

The Octal Serial Peripheral Interface (OSPI) module is a Serial Peripheral Interface (SPI) module which allows

single, dual, quad or octal read and write access to external flash devices. This module has a memory mapped

simplifying software requirements.
