Abstract: An electronic device includes a transaction host, first and second peripherals, memory, an access control register, and first and second access controllers. The memory stores access control identifier management instructions, a first task related to the first peripheral, and a first bitmask indicating respective access settings for the first and second peripherals for performing the first task. The access control register includes a first access control identifier for the first peripheral and a second access control identifier for the second peripheral. The transaction host executes the access control identifier management instructions to program the first and second access control identifiers based on the first bitmask, and subsequently executes the first task. The first and second access controllers control access to the first and second peripherals, respectively, based on the respective first and second access control identifiers programmed based on the first bitmask.
