The differences between the register maps of the DRV8889-Q1 and DRV8889A-Q1 are - DRV8889A-Q1 has
OL_TIME [1:0] and EN_SR_BLANK bits in CTRL5 register to program open-load detection time and slow-decay
to drive mode blanking time. Also, the default value of the DIS_OUT bit in CTRL2 register is different in
DRV8889A-Q1.
Complex bit access types are encoded to fit into small table cells. Table 7-18 shows the codes that are used for
access types in this section.
