DESCRIPTION
READFC1
6
Command to read function-control data from the FC1 register. The 16-bit data
in the FC1 data latch are copied to the common shift register at the falling edge
of the LAT signal. The loaded data can be read out from SOUT synchronized
with the SCLK rising edge.
READFC2
8
Command to read function-control data from the FC2 register. The 16-bit data
in the FC2 data latch are copied to the common shift register at the falling edge
of the LAT signal. The loaded data can be read out from SOUT synchronized
with the SCLK rising edge.
READFC3
10
Command to read function-control data from the FC3 register. The 16-bit data
in the FC3 data latch are copied to the common shift register at the falling edge
of the LAT signal. The loaded data can be read out from SOUT synchronized
with the SCLK rising edge.
READFC4
12
Command to read function-control data from the FC4 register. The 16-bit data
in the FC4 data latch are copied to the common shift register at the falling edge
of the LAT signal. The loaded data can be read out from SOUT synchronized
with the SCLK rising edge.
