Register 19: Extended Control Register 2
The Extended Control Register provides more refined control of the internal ICS1893 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.
The default is the state of this pin at reset.
