Operation Mode.
This bit is used to set the device in Master/Slave operation. Refer to Table 7, “ZL50016
Operating Modes” on page 31 for more details.
Reserved. In normal functional mode, this bits MUST be set to zero.
Input Frame Pulse (FPi) Position
When this bit is low, FPi straddles frame boundary (as defined by ST-BUS).
When this bit is high, FPi starts from frame boundary (as defined by GCI-Bus)
Clock Input (CKi) Polarity
When this bit is low, the CKi falling edge aligns with the frame boundary.
When this bit is high, the CKi rising edge aligns with the frame boundary.
Frame Pulse Input (FPi) Polarity
When this bit is low, the input frame pulse FPi has the negative frame pulse format.
When this bit is high, the input frame pulse FPi has the positive frame pulse format.
Input Clock (CKi) and Frame Pulse (FPi) Selection
The MODE_4M0 and MODE_4M1 pins, as described in “Pin Description” on page 10,
should also be set to define the input clock mode.
Variable Delay Mode Enable
When this bit is low, the variable delay mode is disabled on a device-wide basis.
When this bit is high, the variable delay mode is enabled on a device-wide basis.
Memory Block Programming Enable
When this bit is high, the connection memory block programming mode is enabled to
program the connection memory. When it is low, the memory block programming mode is
disabled.
