Bit 4: Reserved Bit 1 (RSV1). This bit is reserved for future use, it can be written to and read back.
Bits 3 to 0: T0 DPLL Acquisition Bandwidth (T0ABW[3:0]). This field configures the bandwidth of the T0 DPLL
when acquiring lock. When AUTOBW = 0 in the
for locked operation. When AUTOBW = 1,
used for locked operation. See Section 7.7.3.
