When no error occurs in BS1, the bus state shifts to BS2, BS3 and enters Four State Access Mode. When
an error described above occurs, it returns to Two State Access Mode again.
21.8.5 Signal Timing
21.8.5.1 Timing
Timing of SCLK, SDIO and BS
— Sender outputs SDIO signal at SCLK fall (output side), and latches it at SCLK rise (input side).
BS signal is output synchronizing with SCLK fall

TPC is received, however the Memory Stick is not capable of
executing it due to internal status.
When BS1 is under 8 SCLKO.
CRC error occurred in the data transferred from MSHC module.
Not all data are accepted because data state of BS is shorter than the
setting on Memory Stick.
BS is switched before the output of RDY, though Memory Stick is
operating normally.
