ICS1892 Data Sheet
8.11 Register 16: Extended Control Register
Table 8-16 lists the bits for the Extended Control Register, which the ICS1892 provides to allow an STA to
customize the operations of the device.
Note:
1. For an explanation of acronyms used in Table 8-16, 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.
