Chapter 8 Management Register Set
8.14 Register 19: Extended Control Register 2
The Extended Control Register provides more refined control of the internal ICS1892 operations.
Note:
1. For an explanation of acronyms used in Table 8-20, see Chapter 1, “Abbreviations and Acronyms”.
2. During any write operation to any bit in this register, the STA must write the default value to all
Reserved bits.
