DC Fan Controller

t0sn

M.n

Check memory bit and skip next instruction if it’s low

Example:

t0sn

MEM.5 ;

Result: If bit 5 of MEM is low, then skip next instruction

Affected flags: 『N』Z

『N』C

『N』AC

『N』OV

t1sn

M.n

Check memory bit and skip next instruction if it’s high

EX:

t1sn

MEM.5 ;

Result: If bit 5 of MEM is high, then skip next instruction

Affected flags: 『N』Z

『N』C

『N』AC

『N』OV

izsn

Increment ACC and skip next instruction if ACC is zero

Example:

izsn

Result:

a ← a + 1,skip next instruction if a = 0

Affected flags: 『Y』Z

『Y』C

『Y』AC

『Y』OV

dzsn

Decrement ACC and skip next instruction if ACC is zero

Example:

dzsn

Result:

A ← A - 1,skip next instruction if a = 0

Affected flags: 『Y』Z

『Y』C

『Y』AC

『Y』OV

izsn

Increment memory and skip next instruction if memory is zero

Example:

izsn

MEM;

Result:

MEM ← MEM + 1, skip next instruction if MEM= 0

Affected flags: 『Y』Z

『Y』C

『Y』AC

『Y』OV

dzsn

Decrement memory and skip next instruction if memory is zero

Example:

dzsn

MEM;

Result:

MEM ← MEM - 1, skip next instruction if MEM = 0

Affected flags: 『Y』Z

『Y』C

『Y』AC

『Y』OV

wait0

IO.n

Go next instruction until bit n of IO port is low, otherwise, wait here.

Example:

wait0

pa.5;

Result:

Wait bit 5 of port A low to execute next instruction;

Affected flags: 『N』Z

『N』C

『N』AC

『N』OV

Note: This instruction is not supported in single FPP mode.

wait1

IO.n

Go next instruction until bit n of IO port is high, otherwise, wait here.

Example:

wait1

pa.5;

Result:

Wait bit 5 of port A high to execute next instruction;

Affected flags: 『N』Z

『N』C

『N』AC

『N』OV

Note: This instruction is not supported in single FPP mode.
