2.4.2.10 periphSafeAckByOne - clear (acknowledge) bit flags which
are active-high and are cleared by write-one
Call(s):
void periphSafeAckByOne(UWord16 GroupMask, UWord16 Mask,
Arguments:
GroupMask
Mask
pAddr
Description: The periphSafeAckByOne macro clears (acknowledges) bit flags which are
active-high and are cleared by write-one in a peripheral memory location addressed by parameter
pAddr. The GroupMask specifies all flags which might be affected by clearing procedure. The
Mask value specifies flag/flags to be cleared.
Caution: TBD
