BM/P0.0/CMPOUT/PLAI[7]/MS0
Multifunction I/O Pin.
Boot Mode Entry Pin (BM). The ADuC7126 enters UART download mode if BM is low at
reset and executes code if BM is pulled high at reset through a 1 kΩ resistor.. The
ADuC7126 enters I2C download mode in I2C version parts if BM is low at reset with a
flash address of 0x800014 = 0xFFFFFFFFF. The ADuC7126 executes code if BM is pulled
high at reset or if BM is low at reset with a flash address 0x800014 ≠ 0xFFFFFFFFF.
General-Purpose Input and Output Port 0.0 (P0.0).
