8.10.1 Notes When not Using Data Slicer
When bit 0 of data slicer control register 1 (address 00E016) is “0,”
terminate the pins as shown in Figure 8.10.2.
Fig. 8.10.2 Termination of Data Slicer Input/Output Pins when Data Slicer Circuit and Timing Generating Circuit Is in OFF State
When both bits 0 and 2 of data slicer control register 1 (address
00E016) are “1,” terminate the pins as shown in Figure 8.10.3.
