SYNTAX
FUNCTION
DESCRIPTION
curcycles
destination register, rdest.. The master CCCOUNT increments on all cycles (processor-stall and non-stall) if
PCSW.CS = 1; otherwise, the counter increments only on non-stall cycles.
modification of the destination register. If the LSB of rguard is 1, rdest is written; otherwise, rdest is not changed.
