Operation codes

103

The two conditions are evaluated as two NEXT conditions in state.

Conditions inside JMP command:

–

are using only the selected MASKy_A / MASKy_B axis mask;

–

do not affect temporary axis mask pointer;

–

have no peak detection.

The two conditions can be any condition described in this document.

The first step and second step are executed immediately.

Rules for condition validation:

–

COND1 is validated first with new data sample set;

–

If COND1 is not valid, COND2 is validated next;

–

If COND2 is not valid, wait for a new sample set and restart conditions validation;

–

If COND1 is valid, jump to ADD1;

–

If COND2 is valid, jump to ADD2.

This command affects or is affected by the following registers:

–

THRS1_y, THRS2_y: Thresholds limit value;

–

TIM1_y, TIM2_y, TIM3_y, TIM4_y: Timers initial value;

–

MASKy_A and MASKy_B: Axis mask filter values;

–

SETTy, bit ABS: Unsigned/signed settings;

–

SETTy, bit T_SIGN: Temporary output mask filter settings;

–

PRy: Program and Reset pointer addresses.

6.2.4

SRP (33h)

The SRP command sets the Reset Point to the next address/state.

This command has no parameters and it is an “Immediately executed” type.

Actions:

SRP command sets the Reset Point (RPy) to the next step address: RPy = PPy + 1.

This command affects or is affected by the following registers:

–

PRy: Program and Reset pointer addresses.

6.2.5

CRP (44h)

The CRP command clears Reset Point to the start position (at the beginning of the program

code). This command has no parameters and it is an “Immediately executed” type.

Actions:

CRP command sets Reset Point (RPy) to the beginning of program code: RPy = 0.

This command affects or is affected by the following registers:

–

PRy: Program and Reset pointer addresses.
