•nx means the replication of x, n times (that is, x concatenated to itself n – 1 times). n0 and n1 are special
cases:
•n0 means a field of n bits with each bit equal to 0. Thus 50 is equivalent to 0b00000.
•n1 means a field of n bits with each bit equal to 1. Thus 51 is equivalent to 0b11111.
• /, //, ///, ... denotes a reserved field in an instruction or in a register.
• ? denotes an allocated bit in a register.
