DESCRIPTIONS

SDIO Interrupt Value Status
0 = SDIO interrupt at interrupt period. Write 1 to clear this status bit
(set DAT1_IS_ to 1).
1 = no SDIO interrupt at interrupt period.
If SDIO_IEN is set and DAT1_IS_ is 0, an interrupt request will be
generated.
Interrupt period is defined:
(1) If SD data bus width is 1 and DAT[1] is unused, the
interrupt period is any time on DAT[1]
(2) If SD data bus width is 4, the interrupt period is at the
single clock that is 2 clocks after the End bit of data block
SD DAT0 Value
SD Level Transition Status
0=No level transition
1=DAT0 value changes from high to low or low to high. Write 1 to clear
this status bit.
