- * BIAS_DEBOUNCE_B).
- *
- * The values of DEBOUNCE_A and DEBOUNCE_B are calculated as follows:
- *    0xffff -> No debouncing at all
- *    <n> ms = <n> *1000 / (1/19.2MHz) / 4
- *
- * So to program a 1 ms debounce for BIAS_DEBOUNCE_A, we have:
- * BIAS_DEBOUNCE_A[15:0] = 1000 * 19.2 / 4  = 4800 = 0x12c0
- *
- * We need to use only DebounceA for BOOTROM. We don't need the DebounceB
- * values, so we can keep those to default.
- *
- * 4. The 20 microsecond delay after bias cell operation.
