As shown in Figure 16-4 the card uses a busy token during a block write operation. This busy
status is reported by the CBUSY flag in MMSTA register and by the MCBI flag in MMINT which
is set every time CBUSY toggles, i.e. when the card enters and exits its busy state. This flag
may generate an MMC interrupt request as detailed in Section "Interrupt", page 96.
