Notes for Table 5.2.1-23.
[1] The PS (Parameter Savable) bit of 1 indicates that the page 02h parameter data is savable.
[2] A changeable value of zero means this function is not directly changeable by an initiator. A value of 1
means the bit function is directly changeable by an initiator. (See Mode Select command.) See drive
Product Manual Mode Sense data section for table showing changeable values.
[3] Both ratio parameters are the numerators of a fractional multiplier that has 256 (100h) as its denom-
[4] inator.
