SUBWFC

Subtract W and Carry from f

Syntax

SUBWFC f, d

≤ f ≤ FFh

∈ [0,1]

Operation

[Destination]

← [f] – [W] –C

‧

Flag Affected

C, DC, Z

Description

Subtract the content of the W

result is stored in the W

stored back in [f].

Cycle

Example 1:

SUBWFC

OPERAND, 1

Before instruction:

OPERAND = 33h, W =

01h

C = 1

After instruction:

OPERAND = 32h, C = 1, Z

= 0

Example 2:

SUBWFC

OPERAND, 1

Before instruction:

OPERAND = 02h, W =

01h

C = 0

After instruction:

OPERAND = 00h, C = 1, Z

= 1

Example 3:

SUBWFC

OPERAND, 1

Before instruction:

OPERAND = 04h, W =

05h

C = 0

After instruction:

OPERAND = FEh, C = 0, Z =

XORLW

Exclusive OR literal with W

Syntax

XORLW

≤ k ≤ FFh

Operation

[W]

← [W] XOR k

Flag Affected

Description

Exclusive OR the content of

the W register and the

eight-bit literal "k". The result

is stored in the W register.

Cycle

Example:

XORLW

5Fh

Before instruction:

W = ACh

After instruction:

W = F3h

XORWF

Exclusive OR W and f

Syntax

XORWF

f, d

≤ f ≤ FFh

∈ [0,1]

Operation

[Destination]

← [W] XOR [f]

Flag Affected

Description

Exclusive OR the content of

the W register and [f]. If d is

0, the result is stored in the

W register. If d is 1, the

result is stored back in [f].

Cycle

Example:

XORWF

OPERAND, 1

Before instruction:

OPERAND = 5Fh, W =

ACh

After instruction:

OPERAND = F3h

TBLP

Exclusive Programmer EPROM

Syntax

TBLP

k = 32 , that is const

Operation

[EADRH,EADRL]

←EDAH,WORK

Flag Affected

None

Description

Exclusive Programmer EPROM.

EPROM Address is in EADRH

and EADRL.

Programmer Data is in EDAH and

WORK.

Cycle

(k*2)+1

Example:

TBLP

k is const

For FS98O01 Chip , k = 32

MOVP

Exclusive Read EPROM Data

Syntax

MOVP

k is increment EPROM Address

value.

Operation

[EADRH,EADRL] EDAH,WORK

Flag Affected

None

Description

Exclusive Read EPROM data.

EPROM Address is in EADRH

and EADRL. MSB and LSB

After MOVP Data Put in EDAH

and WORK. MSB and LSB

Cycle

Example:

MOVP

After instruction:

EPROM Data put in EDAH

(MSB) and WORK (LSB)

EPROM Address increment k

(EADRH,EADRL)+k
