HMC6352
Waveform Examples
Example 1: This example shows how to read a single byte from the HMC6352. The Slave (HMC6352) continues to hold
the SDA line low after the acknowledge (ACK) bit because the first bit of the data byte is a zero. Remember that the data
read is last command sensitive.
Example 2: This example shows how to read two bytes from the HMC6352 (slave). The slave continues to hold the SDA
line low after the acknowledge bit because the first bit of the data bytes is zero.
Example 3: This example shows how to command HMC6352 to read a RAM register by sending the “g” command and
the register address 7F(hex). Note that this example does not show the process of reading the answer. See example 1
for reading a byte.
Example 4: This example shows how to write to a RAM register in the H MC6352 by sending the “G” command, the
register address 7F(hex), and the data byte 55(hex) to the HMC6352 slave.
