<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. | |||
