It's clear Apple define "Hardware" as "Not using the main CPU". They've pretty much admitted it's firmware based, otherwise the T2 chip simply wouldn't be involved to be mentioned.
- swiftcoder 2y agoThe T2 chip is mentioned in the quoted passage as an indicator of the architecture version, not necessarily an indicator that the T2 chip is directly involved
- dfox 2y agoIt is implemented in dedicated small CPLD that cannot be flashed by any software means. My understanding of relation to T2/SEP is that this CPLD serves as a kind of "IO expander" for T2/SEP which also hardwires logic like this.
