In all cases, Cte must be a decimal value or an expression that can be evaluated immediately.
A_mode can be:
Form Description
[Rn +/-Cte]
Value of rn + or - constant
[Rn +/-Rm]
Value of rn + or – value of rm
[Rn +/-Rm LSL Cte]
[Rn +/-Rm < Cte]
Value of rn + or – value of rm shifted left
[Rn +/-Rm LSR Cte]
[Rn +/-Rm > Cte]
Value of rn + or – value of rm shifted right
[Rn +/-Rm ASR Cte]
[Rn +/-Rm >> Cte]
Value of rn + or – value of rm shifted arithmetically right
[Rn +/-Rm ROR Cte]
[Rn +/-Rm >>> Cte]
Value of rn + or – value of rm rotated right
[Rn +/-Cte]!
Value of rn + or – constant
Rn is updated with that value
[Rn +/-Rm]!
Value of rn + or – value of rm
Rn is updated with that value
[Rn +/-Rm LSL Cte]!
[Rn +/-Rm < Cte]!
Value of rn + or – value of rm shifted left
Rn is updated with that value
[Rn +/-Rm LSR Cte]!
[Rn +/-Rm > Cte]!
Value of rn + or – value of rm shifted right
Rn is updated with that value
[Rn +/-Rm ASR Cte]!
[Rn +/-Rm >> Cte]!
Value of rn + or – value of rm shifted arithmetically right
Rn is updated with that value
[Rn +/-Rm ROR Cte]!
[Rn +/-Rm >>> Cte]!
Value of rn + or – value of rm rotated right
Rn is updated with that value
[Rn] +/-Cte
The value used is the value of rn, but rn is then updated with Value of rn + or –
constant
[Rn] +/-Rm
The value used is the value of rn, but rn is then updated with Value of rn + or –
value of rm
[Rn] +/-Rm LSL Cte
[Rn] +/-Rm < Cte
The value used is the value of rn, but rn is then updated with Value of rn + or –
value of rm shifted left
[Rn] +/-Rm LSR Cte
[Rn] +/-Rm > Cte
The value used is the value of rn, but rn is then updated with Value of rn + or –
value of rm shifted right
[Rn] +/-Rm ASR Cte
[Rn] +/-Rm >> Cte
The value used is the value of rn, but rn is then updated with Value of rn + or –
value of rm shifted arithmetically right
[Rn] +/-Rm ROR Cte
[Rn] +/-Rm >>> Cte
Value of rn + or – value of rm rotated right
Rn is updated with that value
ARMSAT instruction
When using the
ARMSAT
instruction, the Saturn pc is in register r0 and the address chipset structure that contains
the state of the Saturn CPU is in r1.
That structure has the following elements at the following offsets:
Offset Element
0
P_U32 read_map[256+1]; read_map[x] points on the 2Kb of Saturn address space at
Saturn address x<<12
1028
P_U32 write_map[256+1]; read_map[x] points on the 2Kb of Saturn address space
at Saturn address x<<12 for write purpose (write_map[x]=0 if x points on some non
readable memory)
2056
enum ModulePriority top_map[256+1]; // Type of block on top, to know if new
configured block takes over

REG A;
