9.3 I3C header
This header (J18) provides generic access to the I3C interface of the RT595 along with a ground signal. This signals are shared
with the codec and amplifier.
9.4 USART header
Header JP25 is provided as a convenient way to use the USART with a serial to USB cable. Flexcomm 0 ports (P0_1 and P0_2)
are used for this feature, since these ports are assigned for UART ISP mode. These ports are shared with the Link2 debug
probe (LPC4322).
When using this header ensure to disable the connection to the Link2. Disconnect JS27 and short JP4.
NOTE
9.5 High-speed SPI header
Header JP26 provides generic access to the high-speed SPI interface of the RT595 along with a ground signal.
9.6 Additional expansion header
shows the pinout for the additional 10-pin header J47.
