40. SD Host Interface (SDHIa)
40.4
Interrupts
lists the SDHI interrupt sources. When the status flags in registers SDSTS1, SDSTS2, and SDIOSTS become
1, if the corresponding bits in registers SDIMSK1, SDIMSK2, and SDIOIMSK are 0, the SDHI requests an interrupt.
When clearing the status flags in registers SDSTS1, SDSTS2, and SDIOSTS, write 0 to the status flags to be cleared and
write 1 to the states flags not being cleared.
