Part Number: MSP430FE427
Other Parts Discussed in Thread: MSP430F5524

Hi,

We would like to ask you about the function of MSP430 BSL.

Msp430fe427:

1. Whether the BSL of this chip can be customized and reprogrammed;

We can locate the BSL pin of the chip, Data transmit, >, 53-p1.0

Data receiver --->, 52-p1.1

If I want to use this BSL, what should I do with the hardware pin?

3. Do you need a special BSL burner for this function?

Msp430f5524:

1. Whether the BSL of this chip can be customized and reprogrammed;

2. It is found that the BSL of this chip has two interfaces, USB and USART. May I ask how to deal with the hardware pin if I want to use this BSL?

3. This chip BSL can be reprogrammed, may I ask whether the USB and TA_UART interfaces of this BSL can be changed to other ones?Such as USCI_UART;
