NCO-Related Registers
4-17
4.2.17 Register 42
EXT_GAP
Gap Bytes
This value indicates the number of gap bytes applied to
the TS input. These are NCO-related register fields; they
are used only in PLL Mode 2. The reset value is
0b0100 0110.
R/W [7:0]
4.2.18 Register 43
THRESHOLD FIFO Measurement Threshold
This value sets the threshold for the virtual FIFO
measurement, which is used as the initial value for the
autoacquisition. These are NCO-related register fields;
they are used only in PLL Mode 2. The reset value is
0b0111 0011
R/W [7:0]
Table 4.2 shows the reset values for all register fields.
