Execution/behavioural settings for state machine 0

Structs

SM_EXECCTRL_SPEC

Execution/behavioural settings for state machine 0

Enums

STATUS_SEL_A

Comparison used for the MOV x, STATUS instruction.

Type Aliases

EXEC_STALLED_R

Field EXEC_STALLED reader - If 1, an instruction written to SMx_INSTR is stalled, and latched by the state machine. Will clear to 0 once this instruction completes.

INLINE_OUT_EN_R

Field INLINE_OUT_EN reader - If 1, use a bit of OUT data as an auxiliary write enable
When used in conjunction with OUT_STICKY, writes with an enable of 0 will
deassert the latest pin write. This can create useful masking/override behaviour
due to the priority ordering of state machine pin writes (SM0 < SM1 < …)

INLINE_OUT_EN_W

Field INLINE_OUT_EN writer - If 1, use a bit of OUT data as an auxiliary write enable
When used in conjunction with OUT_STICKY, writes with an enable of 0 will
deassert the latest pin write. This can create useful masking/override behaviour
due to the priority ordering of state machine pin writes (SM0 < SM1 < …)

JMP_PIN_R

Field JMP_PIN reader - The GPIO number to use as condition for JMP PIN. Unaffected by input mapping.

JMP_PIN_W

Field JMP_PIN writer - The GPIO number to use as condition for JMP PIN. Unaffected by input mapping.

OUT_EN_SEL_R

Field OUT_EN_SEL reader - Which data bit to use for inline OUT enable

OUT_EN_SEL_W

Field OUT_EN_SEL writer - Which data bit to use for inline OUT enable

OUT_STICKY_R

Field OUT_STICKY reader - Continuously assert the most recent OUT/SET to the pins

OUT_STICKY_W

Field OUT_STICKY writer - Continuously assert the most recent OUT/SET to the pins

R

Register SM_EXECCTRL reader

SIDE_EN_R

Field SIDE_EN reader - If 1, the MSB of the Delay/Side-set instruction field is used as side-set enable, rather than a side-set data bit. This allows instructions to perform side-set optionally, rather than on every instruction, but the maximum possible side-set width is reduced from 5 to 4. Note that the value of PINCTRL_SIDESET_COUNT is inclusive of this enable bit.

SIDE_EN_W

Field SIDE_EN writer - If 1, the MSB of the Delay/Side-set instruction field is used as side-set enable, rather than a side-set data bit. This allows instructions to perform side-set optionally, rather than on every instruction, but the maximum possible side-set width is reduced from 5 to 4. Note that the value of PINCTRL_SIDESET_COUNT is inclusive of this enable bit.

SIDE_PINDIR_R

Field SIDE_PINDIR reader - If 1, side-set data is asserted to pin directions, instead of pin values

SIDE_PINDIR_W

Field SIDE_PINDIR writer - If 1, side-set data is asserted to pin directions, instead of pin values

STATUS_N_R

Field STATUS_N reader - Comparison level for the MOV x, STATUS instruction

STATUS_N_W

Field STATUS_N writer - Comparison level for the MOV x, STATUS instruction

STATUS_SEL_R

Field STATUS_SEL reader - Comparison used for the MOV x, STATUS instruction.

STATUS_SEL_W

Field STATUS_SEL writer - Comparison used for the MOV x, STATUS instruction.

W

Register SM_EXECCTRL writer

WRAP_BOTTOM_R

Field WRAP_BOTTOM reader - After reaching wrap_top, execution is wrapped to this address.

WRAP_BOTTOM_W

Field WRAP_BOTTOM writer - After reaching wrap_top, execution is wrapped to this address.

WRAP_TOP_R

Field WRAP_TOP reader - After reaching this address, execution is wrapped to wrap_bottom.
If the instruction is a jump, and the jump condition is true, the jump takes priority.

WRAP_TOP_W

Field WRAP_TOP writer - After reaching this address, execution is wrapped to wrap_bottom.
If the instruction is a jump, and the jump condition is true, the jump takes priority.
