API429_RM_STACK_READ (0xC2)
P P u u r r p p o o s s e e : :
This function is utilized to read the new stack entries from the monitor stack of the
selected Arinc 429 receiver channel since the last call of the function. Only up to 32
entries can be read. If more then 32 entries are on the stack, the oldest 32 entries
will be read. A stack entry consists of three 32-bit words.
Note: each BIU has its own monitoring buffer. For example an AMC429-32R16
board has one global monitoring buffer for channel 1-16 and one for channel
17-32
