Chapter 8 Management Register Set
8.12 Register 17: Quick Poll Detailed Status Register
Table 8-18 lists the bits for the Quick-Poll Detailed Status Register. This register is a 16-bit read-only
register used to provide an STA with detailed status of the ICS1893AF operations. During reset, it is
initialized to pre-defined default values.
Note:
1. For an explanation of acronyms used in Table 8-18, see Chapter 1, “Abbreviations and Acronyms”.
2. Most of this register’s bits are latching high or latching low, which allows the ICS1893AF to capture and
save the occurrence of an event for an STA to read. (For more information on latching high and latching
low bits, see Section 8.1.4.1, “Latching High Bits” and Section 8.1.4.2, “Latching Low Bits”.)
3. Although some of these status bits are redundant with other management registers, the ICS1893AF
provides this group of bits to minimize the number of Serial Management Cycles required to collect the
status data.
