Note: after the last sample is read from the Y buffer there is a delay of 3 clock cycles before the YEMPTY flag goes high. To avoid any risk of underflow it is recommended to insert a software delay after reading from the Y buffer before reading the FMAC_SR. Alternatively, an EMPTY_WM threshold of 2 can be used.

Note: after the last available space in the X1 buffer is filled there is a delay of 3 clock cycles before the X1FULL flag goes high. To avoid any risk of overflow it is recommended to insert a software delay after writing to the X1 buffer before reading the FMAC_SR. Alternatively, a FULL_WM threshold of 2 can be used.
