ATQ_CTRL2 Register Field Descriptions Bit Field Type Default Description 7-5 ATQ_CNT[10:8] R/W 000b Indicates the 3 MSB bits of the ATQ_CNT output 4-3 RSVD R/W 00b Reserved 2-0 ATQ_LRN_CONST1[10:8] R/W 000b Indicates the 3 MSB bits of the ATQ_LRN parameter at the initial learning current level. 7.5.5.3 ATQ_CTRL3 (address = 0x21) [Default = 00h] ATQ_CTRL3 is shown in Figure 7-90 and described in Table 7-74. Read/Write Return to the Register Maps Table Figure 7-90. ATQ_CTRL3 Register 7 6 5 4 3 2 1 0 ATQ_LRN_CONST1[7:0] R/W-00000000b Table 7-74. ATQ_CTRL3 Register Field Descriptions Bit Field Type Default Description 7-0 ATQ_LRN_CONST1[7:0] R/W 00000000b 8 LSB bits of the ATQ_LRN parameter at the initial learning current level. 7.5.5.4 ATQ_CTRL4 (address = 0x22) [Default = 20h] ATQ_CTRL4 is shown in Figure 7-91 and described in Table 7-75. Read/Write Return to the Register Maps Table Figure 7-91. ATQ_CTRL4 Register 7 6 5 4 3 2 1 0 ATQ_LRN_MIN_CURRENT[4:0] ATQ_LRN_CONST2[10:8] R/W-00100b R/W-000b Table 7-75. ATQ_CTRL4 Register Field Descriptions Bit Field Type Default Description 7-3 ATQ_LRN_MIN_CURRENT[4:0] R/W 00100b Represents the initial current level for auto torque learning. Initial learning current = ATQ_LRN_MIN_CURRENT * 8 2-0 ATQ_LRN_CONST2[10:8] R/W 000b 3 MSB bits of the ATQ_LRN parameter at the final learning current level. 7.5.5.5 ATQ_CTRL5 (address = 0x23) [Default = 00h] ATQ_CTRL5 is shown in Figure 7-92 and described in Table 7-76.
