InTRANS
InM[4:0]
The InTRANS signal encodes information about the transfer. A memory management
unit uses this signal to determine if an access is from a privileged mode. Therefore, you
can use this signal to implement an access permission scheme. The encoding of
InTRANS is shown in Table 4-2.
InM[4:0] indicates the operating mode of the ARM9E-S. This bus corresponds to the
bottom 5 bits of the CPSR, the outputs are inverted with respect to the CPSR.
