5.2.5 _6208_Get_DA_Status
@ Description
This function is used to check the DA data sending status. Because the
data transfer time for every DA data takes 2.2
µ
s, the software driver must
wait for 2.2
µ

function should be called before writing any data to output port. While the
DA value is sending, the returned value is “1”, otherwise the returned value
is “0”.
