What is Shorts Register ? NRF52840

[madhu]

Hi all,
In the Data sheet ,i saw it is a short cut register . It is available for all the peripherals with offset 0x200.

Can you share more information about it, like how it is useful, how to configure it ?

Thanks and Regards R Madhu

Can you provide exact link to nRF52840 Objective Product Specification? Your description is rather cryptic...

i.e., while configuring the UART (content number 49 ) how the shortcut register used ?

This is how HW peripherals can work autonomously with DMA buffers even MCU is not available, see components\drivers_nrf\uart\nrf_drv_uart.c implementation of UARTE Rx init and IRQ handler (shortcut is enabled in nrf_drv_uart_rx_for_uarte function and disabled in uarte_irq_handler - if needed).

Thank you endnode. I try with it.
