No. Variables Note Example
4
Var1 = Var2 * Var3
[Var1, Var2 ] = Var3 * Var4
Multiplication
NX1 does not support second
form.
X1 = R0 * R1,
X1 = R0 * 5
[R0, R1] = R2 * 15
5
Var1 = Var2 / Var3
[Var1, Var2] = Var3 / Var4
Division
In second form, the quotient of
division operation is saved in
Var1, and the remainder is
saved in Var2.
R2 = R0 / 5,
X2 = X1 / R0,
[R2, R1] = R0 / 5
6 Var1 = Var2 % Var3
Remainder operation
R2 = R1 % 15
8 Var++ Increment operation R0++
9 Var-- Decrement operation PA--
10 Var1 = Var2 & Var3 “AND” operation R2 = R0 & R1
11 Var1 = Var2 | Var3 “OR” operation R2 = R0 | R1
12 Var1 = Var2 ^ Var3 “XOR” operation R2 = R0 ^ R1
13 Var1 = Var2 << Var3 Left shift R2 = R0 << 2, R2 = R0 << R1
14 Var1 = Var2 >> Var3 Right shift R2 = R0 >> 2, R2 = R0 >> R1
15 !Var Invert operation !R0, !R0.3
Note:
1. Supported system variables are listed below.
No. Variables
Note Example
1 Vol Volume Vol = R1 + 2
2 Px IO port PA = R0 ^ 0x9
3 V_Chx_Vol The channel volume of voice V_Ch0_Vol = X0
4 M_Chx_Vol The individual channel volume of Melody M_Ch10_Vol = R0
5 SPIVol The channel volume of SPIPlay SPIVol = R0
6 PxM Input / Output mode of IO port PAM = PFM | 0x1
7 PxM.n Input / Output mode of IO pin PAM.0 = PFM.0
8 RandomL
Low nibble of random number
Read only, do not use at the left side of “=”
R0 = RandomL ^ 0x5
9 RandomH
Hight nibble of random number
Read only, do not use at the left side of “=”
R0 = RandomH | 0x9
10 Random
Random number
Read only, do not use at the left side of “=”
X0 = Random ^ 0x33
2. When 1-bit / 4-bit / 8-bit variables are used in variable operation, assigning the variable or
operation result to variable with less bit, the overflow bits would be truncated
Ex. X0 = 0xFA, R3 = X0 ; R3 = 0xA
