MSM66591/ML66592 User's Manual
Chapter 3 CPU Architecture
If the state of DD is changed when a load instruction to ACC or a dedicated set or
reset instruction is executed, the next instruction, if it is an instruction to refers to DD,
is executed referring to the DD whose state has been changed.
Since DD is assigned to PSW, DD can also be changed by instructions other than
the instructions above. In this case, if the next is an instruction to refer to DD, the state
of DD to be changed is referred to in order to execute the instruction. If DD is used in
this manner, insert an NOP instruction, next to the instruction that directly changes the
state of DD.
Bit 11: sign flag (S)
A sign flag is set if MSB is "1", as a result of executing an arithmetic or logic instruc-
tion, and is reset if MSB is "0".
Bit 10: user flag 2 (F2)
Bit 6: user flag 1 (F1)
Bit 3: user flag 0 (F0)
These flags can be set to "1" or "0" depending on the instruction.
Bit 9: overflow flag (OV)
An overflow flag is set to "1" if the result of executing an arithmetic instruction exceeds
the range expressed by a complement of 2 (–128 to +127 in the case of a byte operation;
–32768 to +32767 in the case of a word operation), otherwise it is set to "0".
Bit 8: master interrupt enable flag (MIE)
A master interrupt enable flag controls enable ("1") and disable ("0") of an entire
maskable interrupt. This flag is set to "0" after it is saved to the system stack as PSW
during a maskable interrupt transition cycle, and returns by executing an RTI instruc-
tion. If MIE is set to "1", the generation of an entire maskable interrupt is enabled from
the next instruction. If MIE is set to "0", an entire maskable interrupt is disabled from
the next instruction.
Bit 7: sum of product operation function bank flag (MAB)
Since the MSM66591/ML66592 have no sum of product operation function, MAB can
be used as a user flag.
Bit 5: bank common base 1 (BCB1)
Bit 4: bank common base 0 (BCB0)
Since the MSM66591/ML66592 have no bank common base function, these flags can
be used as user flags.
Bit 2: system control base 2 (SCB2)
Bit 1: system control base 1 (SCB1)
Bit 0: system control base 0 (SCB0)
These flags specify setting the pointing register (PR) assigned to a fixed page area.
