To write to the Configuration Register, follow these steps: 1. Initial conditions: SS* asserted low. SERDATIN = don't care. DAQD*/A = 0 (indicates data will be written to the Configuration Register). SLOT0SEL* = 1. SERCLK = 1 (and has not changed since SS* went low). 2. For each bit, starting with the MSB, perform the following action: a. Set SERDATIN = bit to be sent. These bits are the data that is being written to the Configuration Register. b. Clear SERCLK = 0 c. Set SERCLK = 1. This rising edge clocks the data. If you are using an MIO-16, a write to the EXTSTROBE Register causes EXTSTROBE* to pulse low, thus accomplishing steps b and c.
