AIPSx_PACRn field descriptions (continued)Field Descriptionthe master must be set. If not, access terminates with an error response and no peripheral accessinitiates.0 This peripheral does not require supervisor privilege level for accesses.1 This peripheral requires supervisor privilege level for accesses.17WP3Write protectDetermines whether the peripheral allows write accesss. When this bit is set and a write access isattempted, access terminates with an error response and no peripheral access initiates.0 This peripheral allows write accesses.1 This peripheral is write protected.16TP3Trusted protectDetermines whether the peripheral allows accesses from an untrusted master. When this bit is set and anaccess is attempted by an untrusted master, the access terminates with an error response and noperipheral access initiates.0 Accesses from an untrusted master are allowed.1 Accesses from an untrusted master are not allowed.15ReservedThis read-only field is reserved and always has the value zero.14SP4Supervisor protectDetermines whether the peripheral requires supervisor privilege level for access. When this bit is set, themaster privilege level must indicate the supervisor access attribute , and the MPROTn[MPL] control bit forthe master must be set. If not, access terminates with an error response and no peripheral accessinitiates.0 This peripheral does not require supervisor privilege level for accesses.1 This peripheral requires supervisor privilege level for accesses.13WP4Write protectDetermines whether the peripheral allows write accesss. When this bit is set and a write access isattempted, access terminates with an error response and no peripheral access initiates.0 This peripheral allows write accesses.1 This peripheral is write protected.12TP4Trusted protectDetermines whether the peripheral allows accesses from an untrusted master. When this bit is set and anaccess is attempted by an untrusted master, the access terminates with an error response and noperipheral access initiates.0 Accesses from an untrusted master are allowed.1 Accesses from an untrusted master are not allowed.11ReservedThis read-only field is reserved and always has the value zero.10SP5Supervisor protectTable continues on the next page...Chapter 19 Peripheral Bridge (AIPS-Lite)K51 Sub-Family Reference Manual, Rev. 6, Nov 2011Freescale Semiconductor, Inc. 399
