Symbol

Meaning

 

 

 

 

A~

Select offset accumulator as the source if this bit is 1. Used in opcode encoding only.

 

 

 

 

~A

Select offset accumulator as the destination accumulator if this bit is 1. Used in opcode encod-

 

 

ing only.

 

 

 

 

A~

Select offset accumulator as the source if this bit is 0. Used in opcode encoding only.

 

 

 

 

~A~

Can be either ~A or A~ based on opcode (or instruction). Used in Opcode encoding only.

 

 

 

 

An[~]

Can be either An or An~ where n = 0...3

 

 

 

 

APn

Accumulator Pointer register where n = 0..3. Low-order 5 bits select one of 32 accumulators.

 

 

 

 

adrs

Addressing mode bits am, Rx, pm. See Table 4±46.

 

 

 

 

{adrs}n

Addressing mode which must be provided. It should be of the format shown in Table 4±46. The curly

 

 

braces {} are not included in the actual instruction. The subscript n represents the data size (in bits)

 

 

the instruction will use. For example, {adrs}8 means that the instruction will use 8 bit data from the

 

 

addressed memory and the upper bits may not be used. If n is not provided, data width is 16 bits.

 

ccCondition code bits used with conditional branch/calls and test flag/bit instructions.

{cc}

Conditional code mnemonic used with conditional branch/calls and test flag/bit instructions. Curly

 

braces indicates this field is not optional.

 

 

CF

Carry flag

 

 

clk

Total clock cycles per instruction

 

 

dma[n]

n bit data memory address. For example, dma8 means 8-bit location data memory address. If n is

 

not specified, defaults to dma16.

 

 

DP

Data pointer register, 16 bits

 

 

flagadrs

Flag addressing syntax as shown in Table 4±47.

 

 

flg

Test flag bit. Used in opcode encoding only.

 

 

{flagadrs}

Flag addressing syntax as shown in Table 4±48.

 

 

FM

Fractional mode

 

 

g/r

Global/relative flag bit for flag addressing.

 

 

IM

Interrupt enable mode

 

 

imm[n]

n bit immediate value. If n is not specified, defaults to imm16.

 

 

k0...kn

Constant field bits.

 

 

MR

Multiply register, 16 bits

 

 

next A

Accumulator pointer premodification. See Table 4±45.

 

 

Not

Not condition on conditional jumps, conditional calls or test flag instructions.

 

 

N/R

Not repeatable or not recommended
