CC2340R5-Q1: ROM serial boot loader -- invoke pin, pin level

Tool/software:

Hi,

We would use ROM serial boot loader to program a blank device. I want to double confirm the following are correct:

1. According to TRM 8.5.2 table, the default BSL_invoke pin is DIO21_A10 (Pin No.13 in RHB package). Is that correct?


2. This default BSL_invoke is “active-low digital input used to start the BSL during boot, need to keep low status when programming”. Is that correct?

    That's correct.

    You only need to keep it low long enough to enter the bootloader. However, you can keep it low just in case.

    Best,
