194 / 234 page ![]() CC2430 CC2430 PRELIMINARY Data Sheet (rev. 1.03) SWRS036A Page 194 of 232 14.34.8 Instruction Set Definition There are 14 basic instruction types. Furthermore the Command Strobe and Immediate Strobe instructions can each be divided into eleven sub-instructions giving an effective number of 34 different instructions. The following sub-sections describe each instruction. Note: the following definitions are used in this section PC = CSP program counter X = RF register CSPX Y = RF register CSPY Z = RF register CSPZ T = RF register CSPT 14.34.8.1 DECZ Function: Decrement Z Description: The Z register is decremented by 1. An original value of 0x00 will underflow to 0x0FF. Operation: Z := Z-1 Opcode: 7 6 5 4 3 2 1 0 1 0 1 1 1 1 1 1 14.34.8.2 DECY Function: Decrement Y Description: The Y register is decremented by 1. An original value of 0x00 will underflow to 0x0FF. Operation: Y := Y-1 Opcode: 7 6 5 4 3 2 1 0 1 0 1 1 1 1 1 0 14.34.8.3 INCY Function: Increment Y Description: The Y register is incremented by 1. An original value of 0x0FF will overflow to 0x00. Operation: Y := Y+1 Opcode: 7 6 5 4 3 2 1 0 1 0 1 1 1 1 0 1 14.34.8.4 INCMAXY Function: Increment Y not greater than M. Description: The Y register is incremented by 1 if the result is less than M otherwise Y register is loaded with value M. Operation: Y:= min(Y+1, M) Opcode: 7 6 5 4 3 2 1 0 1 0 1 1 0 M 14.34.8.5 RANDXY Function: Load random value into X Description: The [Y] LSB bits of X register are loaded with random value. Note that if two RANDXY instructions are issued immediately after each other the same random value will be used in both cases. Operation: X[Y-1:0]:= RNG_DOUT[Y- 1:0], X[7:Y] := 0 Opcode: 7 6 5 4 3 2 1 0 1 0 1 1 1 1 0 0 |
