==== chmod ====
<code>00000000: f5 3c XY a8 cchmod $cY 0X</code> or <code>00000000: f5 3c XY a9 cchmod $cY 1X</code>
This instruction takes a crypto register and a 5 bit immediate value which represents the [[#ACLs|ACLs]] mask to set.
==== sigcmp ====
<code>00000000: f5 3c XY d8 csigcmp $cY $cX</code>
Takes 2 crypto registers as operands and is automatically executed when jumping to a code region previously uploaded as secret. This instruction does not work in secure mode.
==== sigclr ====
<code>00000000: f5 3c 00 e0 csigclr</code>
This instruction takes no operands and clears the saved cauth signature used by the csigenc instruction.
