The reset value is a reset configuration word value, extracted from the indicated internal data bus line. Refer to
“Hard Reset Configuration Word (RCW)
.”

16
PRPM
Peripheral mode. In this mode, the internal RCPU core is shut off and an alternative master on
the external bus can access any internal slave module. The reset value of this bit is determined
by the reset configuration word bit 16. The bit can also be written by software.
0 Normal operation
1 Peripheral mode operation
17
SLVM
Slave mode (valid only if PRPM = 0). In this mode, an alternative master on the external bus can
access any internal slave module while the internal RCPU core is fully operational. If PRPM is
set, the value of SLVM is a “don’t care.”
0 Normal operation
1 Slave mode

SIZE
Size attribute. If SIZEN = 1, the SIZE bits controls the internal bus attributes as follows:
00 Double word (8 bytes)
01 Word (4 bytes)
10 Half word (2 bytes)
11 Byte
21
SUPU
Supervisor/user attribute. SUPU controls the supervisor/user attribute as follows:
0 Supervisor mode access permitted to all registers
1 User access permitted to registers designated “user access”
22
INST
Instruction attribute. INST controls the internal bus instruction attribute as follows:
0 Instruction fetch
1 Operand or non-CPU access

Reserved
25
RESV
Reservation attribute. RESV controls the internal bus reservation attribute as follows:
0 Storage reservation cycle
1 Not a reservation
