Syntax:

• LUTLSB Rd3 BS Rs1

Description:

Returns in register Rd3 the leading term of iterative algorithm to get 1/x, where x is the content of Rs1. Instruction is performed according to BS (bank select)and is stack conditioned.

Microcode Pattern:

Takes 4 cycles to execute.
    Example: LUTLSB 0xA3 3 0xA1

	  
	MPC  BS3 C3 P3 P1
