2.6
In the SH7708R, operations may not be performed correctly when the following sequences are
executed with the cache on.
Notes: 1. MULS.W, MULU.W, MAC.L, MAC.W, DMULS.L, DMULU.L, MUL.L, MULS.W,
Software Remedy: This problem can be avoided in either of the following ways.
1. Do not use the above sequences.
2. When performing STS/LDS on the MACL/MACH register after consecutive execution of MAC
50
instructions, insert an NOP instruction between the MAC instructions and STS/LDS
instruction.
2. BF, BF/S, BT, BT/S, BRA, BRAF, BSR, BSRF, JMP, JSR, RTS
