CALL
Subroutine Call
Syntax:
[
label ] CALL k
Operands:
0
≤ k ≤ 255
Operation:
(PC) + 1
→ Top of Stack;
k
→ PC<7:0>;
(STATUS<6:5>)
→ PC<10:9>;
0
→ PC<8>
Status Affected:
None
Encoding:
1001
kkkk
Description:
Subroutine call. First, return address
(PC+1) is pushed onto the stack. The
eight bit immediate address is loaded
into PC bits <7:0>. The upper bits
PC<10:9> are loaded from STA-
TUS<6:5>, PC<8> is cleared. CALL is
a two cycle instruction.
Words:
1
Cycles:
2
Example:
HERE
CALL
THERE
Before Instruction
PC =
address (HERE)
After Instruction
PC =
address (THERE)
TOS =
address (HERE + 1)
CLRF
Clear f
Syntax:
[
label ] CLRF
f
Operands:
0
≤ f ≤ 31
Operation:
00h
→ (f);
1
→ Z
Status Affected:
Z
Encoding:
0000
011f
ffff
Description:
The contents of register ’f’ are cleared
and the Z bit is set.
Words:
1
Cycles:
1
Example:
CLRF
FLAG_REG
Before Instruction
FLAG_REG
=
0x5A
After Instruction
FLAG_REG
=
0x00
Z=
1
CLRW
Clear W
Syntax:
[
label ] CLRW
Operands:
None
Operation:
00h
→ (W);
1
→ Z
Status Affected:
Z
Encoding:
0000
0100
0000
Description:
The W register is cleared. Zero bit (Z)
is set.
Words:
1
Cycles:
1
Example:
CLRW
Before Instruction
W
=
0x5A
After Instruction
W
=
0x00
Z=
1
CLRWDT
Clear Watchdog Timer
Syntax:
[
label ] CLRWDT
Operands:
None
Operation:
00h
→ WDT;
0
→ WDT prescaler (if assigned);
1
→ TO;
1
→ PD
Status Affected:
TO, PD
Encoding:
0000
0100
Description:
The CLRWDT instruction resets the
WDT. It also resets the prescaler, if the
prescaler is assigned to the WDT and
not Timer0. Status bits TO and PD are
set.
Words:
1
Cycles:
1
Example:
CLRWDT
Before Instruction
WDT counter =
?
After Instruction
WDT counter =
0x00
WDT prescale =
0
TO
=1
PD
=1
