Reserved. These bits must be written to their reset
default value (0x000).
General-Purpose Output Values. The value writ-
ten into these bits will appear on the GPIO[3:0] pins.
Reserved. These bits must be written to their reset
default value (000).
Packet/ATM Over Fiber/SONET. 0 = packet or ATM
over fiber (POF); 1 = packet or ATM over SONET
(POS).
Reserved. These bits must be written to their reset
default value (00).
Performance Monitoring Mode.
00 or 10 = PMRST comes from external pin.
01 = PMRST comes from internal 1-second counter.
11 = PMRST is software controlled.
SDH or SONET Mode. 1 = SDH; 0 = SONET.
Clear-on-Read or Clear-on-Write Control. This bit
sets the functionality of the COR/W registers.
1 = COR. Clear on read; read register to clear.
0 = COW. Clear on write; write 1 to clear.
COW mode will clear bits to which a 1 is written. Bits
written to 0 are not cleared.
PLL Mode. Control for STS-48/STM-16 mode only.
This bit controls the transmit line clock PLL. For
STS-48/STM-16 contra-clocking mode, this PLL
must be active, i.e., the bit = 0.
1 = PLL off (inactive)
0 = PLL on (active)
STS-48/STM-16 Control. 1 = STS-48/STM-16
mode; 0 = STS-3/STS-12 (STM-1/STM-4) mode.
STS-12/STS-3 (STM-4/STM-1) Mode Control.
The only values permitted are the following:
1111 = STS-12/STM-4
0000 = STS-3/STM-1
