20.4.6 Branch and control instructions
Test bits.
TST Rn, Rm
where:
This instruction tests the value in a register against another register. It updates the
condition flags based on the result, but does not write the result to a register.
The TST instruction performs a bitwise AND operation on the value in Rn and the value in
Rm. This is the same as the ANDS instruction, except that it discards the result.
To test whether a bit of Rn is 0 or 1, use the TST instruction with a register that has that bit
set to 1 and all other bits cleared to 0.
In these instructions, Rn and Rm must only specify R0-R7.
This instruction:

Table 234. Branch and control instructions
Mnemonic
B{cc}
•
•
Rn is the register holding the first operand.
Rm the register to test against.
SXTH R4, R6
updates the N and Z flags according to the result
does not affect the C or V flags.
TST
UXTB R3, R1
shows the branch and control instructions:
R0, R1 ; Perform bitwise AND of R0 value and R1 value,
