intervention

Dual Synchronous Serial Ports (for SPI, MMC, SDIO, Triflash)
— 1-bit, 4-bit and 8-bit MMC/SD/SDIO modes
— Compliant with SDIO Rev. 2.0
— SPI with single, dual and quad modes.

Four-Channel 16-Bit Timer with Rotary Decoder

Five-Channel Pulse Width Modulator (PWM)

Real-Time Clock
— Alarm clock can turn the system on.
— Uses the existing 24-MHz XTAL for low cost or optional low power crystal (32.768 kHz
or 32.0 kHz), customer-selectable via OTP.

Customer-Programmable One-Time-Programmable (OTP) ROM via Integrated eFuse Block
— Resistor-less boot mode selection
— 128-bit boot mode crypto key
— Boot mode specification of NAND characteristics for device that the customer is
soldering to the board. This means no more costly delays waiting for new device support in t
he boot ROM.
— Fully software-programmable and accessible

Flexible I/O Pins
— All digital pins have drive-strength controls
— Most non-EMI digital pins have general-purpose input/output (GPIO) mode.
