6. Program counter during repeat control
Table 3.7
Note: In table 3.7, the following labels are used.
RptDtct
RptDtct1 RptDtct1 + 4
RptDtct2
RptDtct3
If RC[11:0] ≥ 2, the program counter (PC) value is not correct for instructions two instructions
following a repeat detection instruction. In a repeat loop consisting of one to three instructions,
the PC indicates the correct value (instruction address + 4) for an instruction (repeat start
instruction) following a repeat detection instruction but the PC continues to indicate the same
address (repeat start instruction address) from the subsequent instruction to a repeat end
instruction. In a repeat loop consisting of four or more instructions, the PC indicates the correct
value (instruction address + 4) for an instruction following a repeat detec-tion instruction, but
PC indicates the RS and (RS +2) for instructions two and three instructions following the
repeat detection instruction. Here, RS indicates the value stored in the repeat start register
(RS). The correct operation cannot be guaranteed for the incorrect PC values.
Accordingly, PC relative addressing instructions placed two or more instructions following the
repeat detection instruction cannot be executed correctly and the correct results cannot be
obtained.
