3.4.2.3 Control Commands
These commands are used to control the program flow (loops, conditions, jumps etc.). It does not make
sense to use them in direct mode. They are intended for standalone mode only.

Compare accumulator with constant

CSUB
23
Call subroutine
RSUB
24
Return from subroutine
WAIT
27
Wait for a specified event
STOP
28
End of a TMCL program
3.4.2.4 I/O Port Commands
These commands control the external I/O ports and can be used in direct mode and in standalone mode.

SIO
14

GIO
15
Get input
3.4.2.5 Calculation Commands
These commands are intended to be used for calculations within TMCL applications. Although they could
also be used in direct mode it does not make much sense to do so.
Mnemonic
Command number
Meaning
CALC
19
Calculate using the accumulator and a
constant value
CALCX
33
Calculate using the accumulator and the
X register
AAP
34
Copy accumulator to an axis parameter
AGP
35
Copy accumulator to a global parameter
ACO
39
Copy accu to coordinate
For calculating purposes there is an accumulator (or accu or A register) and an X register. When executed
in a TMCL program (in standalone mode), all TMCL commands that read a value store the result in the
accumulator. The X register can be used as an additional memory when doing calculations. It can be
loaded from the accumulator.
When a command that reads a value is executed in direct mode the accumulator will not be affected.
This means that while a TMCL program is running on the module (standalone mode), a host can still
send commands like GAP and GGP to the module (e.g. to query the actual position of the motor) without
affecting the flow of the TMCL program running on the module.
3.4.2.6 Interrupt Commands
Due to some customer requests, interrupt processing has been introduced in the TMCL firmware for ARM
based modules.
