Default: 0x010D
DESCRIPTION
Serdes RX rate settings
00 = Full rate (Default 2’b00)
01 = Half rate
10 = Quarter rate
11 = Eighth rate
Values written are valid only when RATE_A/B[2:0] pins are set to 3’b100 and ARS is not
enabled (10.13:12 = 2’b00)
In ARS mode, values written to these bits are not considered to determine serdes RX rate.
Instead it is automatically determined by ARS machine.
When read, these bits will reflect the final serdes Rx rate values
Serdes PLL multiplier setting (Default 4’b1101). In ARS mode, values written to these bits is
not considered to determine serdes PLL multiplier. Instead it is automatically determined by
ARS machine and these bits when read will reflect that value.
Refer Table 3-3
