Freescale Semiconductor 30-43
For all types of exception processing, the PST = 0xC value is driven at all times, unless the PST output is
needed for one of the optional marker values or for the taken branch indicator (0x5).
Table 30-23 shows the PST/DDATA specification for multiply-accumulate instructions.
30.7.2 Supervisor Instruction Set
The supervisor instruction set has complete access to the user mode instructions plus the opcodes shown
below. The PST/DDATA specification for these opcodes is shown in
Table 30-24 .
