where the {...} definition is optional operand information defined by the setting of the CSR.
The CSR provides capabilities to display operands based on reference type (read, write, or both). A PST
value {0x08, 0x09, or 0x0B} identifies the size and presence of valid data to follow in the PST trace buffer
(PSTB) {1, 2, or 4 bytes}. Additionally, for certain change-of-flow instructions, CSR[BTB] provides the
capability to display the target instruction address in the PSTB {2 or 3 bytes} using a PST value of {0x0D
or 0x0E}.
18.4.3.4.1 User Instruction Set
Table 18-27 shows the PST/DDATA specification for user-mode instructions. Rn represents any {Dn, An}
register. In this definition, the y suffix generally denotes the source, and x denotes the destination operand.
For a given instruction, the optional operand data is displayed only for those effective addresses
referencing memory. The DD nomenclature refers to the DDATA outputs.
