10. INSTRUCTION SET OVERVIEW
The instruction set for the
PD789322, 789324, 789326, and 789327 are listed in this section.
10.1 Conventions
10.1.1 Operand formats and descriptions
The description made in the operand field of each instruction conforms to the operand format for the instructions
listed below (the details conform to the assembly specification). If more than one operand format is listed for an
instruction, one is selected. Uppercase letters, #, !, $, and brackets [ ] are used to specify keywords, which must be
written exactly as they appear. The meanings of these special characters are as follows:
#: Immediate data specification
$: Relative address specification
!: Absolute address specification
[ ]: Indirect address specification
Immediate data should be described using appropriate values or labels. The specification of values and labels
must be accompanied by #, !, $, or [ ].
Operand registers, expressed as r or rp in the formats, can be described using both functional names (X, A, C,
etc.) and absolute names (R0, R1, R2, and other names listed in Table 5-1 below).
