23.0 Detailed Register Description
Bit
Name
Description
15 - 14
Unused
Reserved.
In normal functional mode, these bits
MUST
be set to zero.
13
SLV_
DPLLEN
DPLL Enable in Slave Mode (ignored in Master Mode)
When this bit is low, DPLL is disabled in Slave mode.
When this bit is high and OSC_EN = 1, the DPLL is enabled in Slave mode.
When SLV_DPLLEN is set in Slave mode, CKo[3:0] and FPo[3:0] are generated from
CKi and FPi. CKo[5:4] and FPo[5] are locked to the selected input reference (one of
REF[3:0]). In this mode of operation, the DPLL retains its functionality, including the
generation of the REF_FAIL[3:0] output signals. See Table 7, “ZL50018 Operating
Modes” on page 37 for more details.
12 - 11
OPM1 - 0
Operation Mode
These bits are used to set the device in Master/Slave operation. Refer to Table 7,
“ZL50018 Operating Modes” on page 37 for more details.
10
CKi_LP
CKi and FPi Loopback (Ignored in Slave mode)
When this bit is low, CKi and FPi are used as input pins.
When this bit is high, CKi and FPi are internally looped back from CKo2 (16.384 MHz)
and FPo2 respectively, and CKi pin and FPi pin should be tied low or high externally;
CKIN1 - 0 (bits 6 - 5) of this register should be programmed to be 00. See Table 7,
“ZL50018 Operating Modes” on page 37 for more details.
9
FPINPOS
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)
8
CKINP
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.
7
FPINP
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.
6 - 5
CKIN1 - 0
Input Clock (CKi) and Frame Pulse (FPi) Selection
The MODE_4M0 and MODE_4M1 pins, as described in “Pin Description” on page 13,
should also be set to define the input clock mode.
