Following registers are RDOC operation registers. These registers excluding RDOC_7[1:0],
RDOC_8[1:0] bits must be in the default setting. RDOC_7[1:0], RDOC_8[1:0] bits must be set to “11”

KEEP_RDOC: Interlock Setting with AGC KEEP Function
The RDOC function can be interlocked with the AGC KEEP function by setting this bit. If this bit is “1”,
the RDOC cancellation function will be OFF when setting the AGC_KEEP pin = “H” or AGC_KEEPR =
“1”. In this time, the calculated DC offset value is kept. The RDOC function will be enabled again when
setting the AGC_KEEP pin = “L” or AGC_KEEPR bit = “0”.
0: Do Not Interlock RDOC Function with AGC KEEP Function
1: Interlock RDOC Function with AGC KEEP Function
