9.39.3 Assembler Directives
---------------------------
The RX version of 'as' has the following specific assembler directives:
'.3byte'
Inserts a 3-byte value into the output file at the current
location.
'.fetchalign'
If the next opcode following this directive spans a fetch line
boundary (8 byte boundary), the opcode is aligned to that boundary.
If the next opcode does not span a fetch line, this directive has
no effect. Note that one or more labels may be between this
directive and the opcode; those labels are aligned as well. Any
inserted bytes due to alignment will form a NOP opcode.
