4 Peripherals

– Decoding current or voltage amplitude derived from duty-cycle-encoded signals of current/voltage

sensors

– Three individual capture channels, each of which with a 32-bit time-stamp register

– Selection of edge polarity and prescaling of input capture signals

– The capture timer can sync with a PWM timer or external signals

For details, see ESP32 Technical Reference Manual > Chapter Motor Control PWM.

Pin Assignment

The pins for the Motor Control PWM can be chosen from any GPIOs via the GPIO Matrix.

For more information about the pin assignment, see ESP32 Series Datasheet > Section Peripheral Pin

Configurations and ESP32 Technical Reference Manual > Chapter IO_MUX and GPIO Matrix.

4.2.10

SD/SDIO/MMC Host Controller

An SD/SDIO/MMC host controller is available on ESP32.

Feature List

• Supports two external cards

• Supports SD Memory Card standard: version 3.0 and version 3.01)

• Supports SDIO Version 3.0

• Supports Consumer Electronics Advanced Transport Architecture (CE-ATA Version 1.1)

• Supports Multimedia Cards (MMC version 4.41, eMMC version 4.5 and version 4.51)

The controller allows up to 80 MHz clock output in three different data-bus modes: 1-bit, 4-bit, and 8-bit

modes. It supports two SD/SDIO/MMC4.41 cards in a 4-bit data-bus mode. It also supports one SD card

operating at 1.8 V.

For details, see ESP32 Technical Reference Manual > Chapter SD/MMC Host Controller.

Pin Assignment

The pins for SD/SDIO/MMC Host Controller are multiplexed with GPIO2, GPIO4, GPIO6 ~ GPIO15 via IO

MUX.

Configurations and ESP32 Technical Reference Manual > Chapter IO_MUX and GPIO Matrix.

4.2.11 SDIO/SPI Slave Controller

ESP32 integrates an SD device interface that conforms to the industry-standard SDIO Card Specification

Version 2.0, and allows a host controller to access the SoC, using the SDIO bus interface and protocol. ESP32

acts as the slave on the SDIO bus. The host can access the SDIO-interface registers directly and can access

shared memory via a DMA engine, thus maximizing performance without engaging the processor cores.
