Channel suspend: When the channel suspend event action is selected, the event input is used to suspend an ongoing
channel operation. The event is acknowledged when the current AHB access is completed. For further details on channel
suspend, refer to “Channel Suspend” on page 285.
Channel resume: When the channel resume event action is selected, the event input is used to resume a suspended
channel operation. The event is acknowledged as soon as the event is received and the Channel Suspend Interrupt Flag
(CHINTFLAG.SUSP) is cleared. For further details on channel suspend, refer to “Channel Suspend” on page 285.
Skip next block suspend: This event can be used to skip the next block suspend action. If the channel is suspended
before the event rises, the channel operation is resumed and the event is acknowledged. If the event rises before a
suspend block action is detected, the event is kept until the next block suspend detection. When the block transfer is
completed, the channel continues the operation (not suspended) and the event is acknowledged.
