POP

√

Pop Top of Stack to Low Accumulator

Copy the contents of the top of the stack into the 12

(TMS320C1x) or 16 (TMS320C2x/2xx/5x) LSBs of the

accumulator and then pop the stack one level. The

MSBs of the accumulator are zeroed.

POPD

dma

POPD {

ind} [, next ARP]

√

Pop Top of Stack to Data Memory

Transfer the value on the top of the stack into the

addressed data-memory location and then pop the

stack one level.

PSHD

dma

PSHD {

ind} [, next ARP]

√

Push Data-Memory Value Onto Stack

Copy the addressed data-memory location onto the

top of the stack. The stack is pushed down one level

before the value is copied.

PUSH

√

Push Low Accumulator Onto Stack

Copy the contents of the 12 (TMS320C1x) or 16

(TMS320C2x/2xx/5x) LSBs of the accumulator onto

the top of the hardware stack. The stack is pushed

down one level before the value is copied.

√

Reset Carry Bit

Reset the C status bit to 0.

RET

√

Return From Subroutine

Copy the contents of the top of the stack into the PC

and pop the stack one level.

RET[

√

Return From Subroutine With Optional Delay

Copy the contents of the top of the stack into the PC

and pop the stack one level.

If you specify a delayed branch (RETD), the next two

instruction words (two 1-word instructions or one

2-word instruction) are fetched and executed before

the return.

RETC

cond1 [, cond2] [, ...]

√

Return Conditionally

If the specified conditions are met, RETC performs a

standard return. Not all combinations of conditions are

meaningful.
