29:16 | 0000h | RO/V | Captured Frame List Current Index/Frame Number (CMFI) The value in this register is updated in response to sample_now signal. Bits (29:16) reflect state of bits (13:0) of FRINDEX |
15:13 | - | - | Reserved
|
12:0 | 0000h | RO/V | Captured Micro-frame BLIF (CMFB) The value is updated in response to sample_now signal and provides information about offset within micro-frame. Captured value represents number of 8 high-speed bit time units from start of micro-frame. At the beginning of micro-frame captured value will be 0 and increase to maximum value at the end. Default maximum value is 7499 but it may be changed as result of adjustment done in FLA. |
