NOTE:
1. n denotes an input stream number from 0 to 7.
Name(1)
Description
OFn2, OFn1, OFn0
These three bits define how long the serial interface receiver takes to recognize and store bit 0 from the RX input pin: i.e., to
(Offset Bits 2, 1 & 0)
start a new frame. The input frame offset can be selected to +4.5 clock periods from the point where the external frame pulse
input signal is applied to the
F0i input of the device. See Figure 5.
DLEn
(Data Latch Edge)
ST-BUS mode:
DLEn = 0, if clock rising edge is at the point of the bit cell.
DLEn = 1, if when clock falling edge is at the of the bit cell.
GCI mode:
DLEn = 0, if clock falling edge is at the point of the bit cell.
DLEn = 1, if when clock rising edge is at the of the bit cell.
Read/Write Address:
03H for FOR0 register,
04H for FOR1 register.
Reset Value:
0000H for all FOR registers.
