Command summary 14.3.1 Register read command The device supports a Register Read command. The Register Read command uses the upper 7 bits of the addresses defined in Section 11.1 to address two 8-bit registers in the register map. The response to the command includes the con-tents of RA[7:1] high byte (RA[0] = 1) in the upper byte and the contents of RA[7:1] low byte (RA[0] = 0) in the lower byte. The response to a register read command is shown in Section 14.3.1.2. The response is transmitted on the next SPI message if and only if all of the following conditions are met: • No SPI Error is detected (See Section 14.5.6) • No MISO Error is detected (See Section 14.5.7) If the conditions are met, the device responds to the register read request as shown in Section 14.3.1.2. Otherwise, the device responds with the Error Response as defined in FXLS9xxxx All information provided in this document is subject to legal disclaimers. © NXP B.V. 2021. All rights reserved.
