Table 4-5. Diagnostic Parameters
Index R/W Description Default
0x708 R + W 0x0 = Normal operation
0x1 = LLB
0x2 = RLB
0x5 =TAIS, transmit AIS
1. Normal operation after reset
2. No time out for loops
XXXX X000
Normal operation
4.6 Typical Examples
Reading LCVCR 1 statistic for T1
1. I
2
C Control and Write bits in the first byte
2. Next byte with content of 0x80 (as the first address).
3. Next byte with the First byte of the Index (MSB) – 0x06.
4. Next byte with the Second Index byte of the Index (LSB) – 0x72.
5. Next byte contains 0x01 for a read operation.
6. Byte with content of 0x01 for the Length (in this example the parameter
Length is one byte)
To read the required byte, the host sends a new I2C message with the following
structure:
1. I
2
C control bits and read bit in the first byte
2. Next byte with content of 0x84 (for the first address).
3. In response, MiRIC sends the contents of address 0x84 (message per byte) to
the host equipment.
Configuring LLB
1. I
2
C control and Write bits in the first byte
2. Next byte is 0x80 (the first address)
3. Next byte contains the first byte of the Index (MSB) parameter – 0x07.
4. Next byte contains the second Index byte (LSB) parameter – 0x08.
