4 Functional Description

• Using the video mode to output video stream

• Outputting image patterns

Pin Assignment

The MIPI DSI interface uses the dedicated digital pins 34–40.

4.2.2

Connectivity Interface

This subsection describes the connectivity interfaces on the chip that enable communication and interaction

with external devices and networks.

4.2.2.1 UART Controller (UART)

ESP32-P4 has six UART controllers, including five UARTs in the HP system and one low-power (LP)

UART.

Software and hardware flow control

Three prescalable clock sources:

1. XTAL_CLK

2. RC_FAST_CLK

3. PLL_F80M_CLK

Three prescalable clock sources

1. RC_FAST_CLK

2. XTAL_DIV_CLK

3. PLL_F8M_CLK

Pin Assignment

For UART0–UART4 interfaces, the pins used can be chosen from any GPIOs via the GPIO Matrix. By default,

the pins connected to transmit and receive signals (UART0_TXD_PAD and UART0_RXD_PAD) of UART0 are

multiplexed with GPIO37–GPIO38 and the eight-line interface of SPI2 controller via IO MUX.
