¡: XWAIT sampling in SH3 mode
×: Soft Wait (1 cycle) in SH3 mode
T1: Read/write start cycle (XRDY in wait state)
Tsw*: Software wait insertion cycle (1 cycle setting)
Thw*: Hardware wait insertion cycle (XRDY cancels the wait state after the preparations)
T2: Read/write end cycle (XRDY ends in wait state)
