MSP430FR2632: erased/disabled BSL behavior on BSL entry sequence

Hello,

I had a question on the behavior of an MSP430FR2632 with an empty or disabled BSL region. The TRM says that any attempt to access this region if the bootloader is disabled is treated as a vacant memory access and will trigger an NMI. 

So what happens if the BSL entry sequence is invoked on a device with the bootloader disabled? Does it jump directly into the NMI vector? Or is this treated as a PUC/ reset of some sort?
