8.17.2 Syntax

In the M68HC11 syntax, the instruction name comes first and it may be followed by one or several operands (up to three). Operands are separated by comma (`,'). In the normal mode, as will complain if too many operands are specified for a given instruction. In the MRI mode (turned on with `-M' option), it will treat them as comments. Example:

lda  #23
bset 2,x #4
brclr *bot #8 foo

The following addressing modes are understood:


Address Register
`number,X', `number,Y'

The number may be omitted in which case 0 is assumed.

Direct Addressing mode
`*symbol', or `*digits'

`symbol', or `digits'
