The trap instruction is an unconditional trap:

trap

Examples

To trap if R10 is less than R20:
```
tlt   10, 20
```
This is equivalent to:
```
t   16, 10, 20
```
To trap if R4 is equal to 0x10:
```
teqi   4, 0x10
```
This is equivalent to:
```
ti   0x4, 4, 0x10
```
To trap unconditionally:
```
trap
```
This is equivalent to:
```
tw   31, 0, 0
```
To trap if RX is not equal to RY:
```
twnei   RX. RY
```
This is equivalent to:
```
twi   24, RX, RY
```
To trap if RX is logically greater than 0x7FF:
```
twlgti   RX, 0x7FF
```
This is equivalent to:
```
twi   1, RX, 0x7FF
```
