GIC

Generic Interrupt Controller

This instruction manages interrupts when FEAT_GCIE is implemented.

This is an alias of SYS. This means:

System class

(FEAT_GCIE)

313029282726252423222120191817161514131211109876543210

LCRn

Encoding

(CRm IN {0001, 0010})

GIC <gic_op>{, <Xt>}

is equivalent to

SYS #<op1>, C12, <Cm>, #<op2>{, <Xt>}

and is the preferred disassembly when SysOp(op1, '1100', CRm, op2) == Sys_GIC.

Assembler Symbols

<gic_op>

Is a GIC operation name, as listed for the GIC system instruction group, encoded in (op1 :: CRm :: op2):
