COMMON OPERATIONAL CONTROLS (REGISTER 0x0A00 TO REGISTER 0x0A0E)
Table 145. Global Operational Controls
Address Bits Bit Name Description
0x0A00
[7:3]
Reserved
Default: 00000b.
2 Soft sync all Setting this bit initiates synchronization of all clock distribution outputs (default = 0b).
Nonmasked outputs stall when value is 1; restart is initialized on a 1-to-0 transition.
1 Calibrate all Calibrates both output PLL0 (APLL_0) and output PLL1 (APLL_1).
0 Power down all Places the entire device in deep sleep mode (default: device is not powered down).
Table 146. Reference Input Power-down
Address Bits Bit Name Description
0x0A01 [7:4] Reserved Default: 0x0
3
REFD power-down
Powers down REFD input receiver
0 (default) = not powered down
1 = powered down
2 REFC power-down Powers down REFC input receiver
0 (default) = not powered down
1 = powered down
1 REFB power-down Powers down REFB input receiver
0 (default) = not powered down
1 = powered down
0 REFA power-down Powers down REFA input receiver
0 (default) = not powered down
1 = powered down
Table 147. Reference Input Validation Timeout
Address Bits Bit Name Description
0x0A02 [7:4] Reserved Default: 0x0
3 REFD timeout
(autoclear)
If REFD is unfaulted, setting this autoclearing bit forces the reference validation timer for
REFD to zero, thus making it valid immediately (default = 0b).
2 REFC timeout
(autoclear)
If REFC is unfaulted, setting this autoclearing bit forces the reference validation timer for
REFC to zero, thus making it valid immediately (default = 0b).
1 REFB timeout
(autoclear)
If REFB is unfaulted, setting this autoclearing bit forces the reference validation timer for
REFB to zero, thus making it valid immediately (default = 0b).
0 REFA timeout
(autoclear)
If REFA is unfaulted, setting this autoclearing bit forces the reference validation timer for
REFA to zero, thus making it valid immediately (default = 0b).
Table 148. Force Reference Input Fault
Address Bits Bit Name Description
0x0A03 [7:4] Reserved Default: 0x0
3 REFD fault Faults REFD input receiver
0 (default) = not faulted
1 = faulted (REFD is not used)
2 REFC fault Faults REFC input receiver
0 (default) = not faulted
1 = faulted (REFC is not used)
1 REFB fault Faults REFB input receiver
0 (default) = not faulted
1 = faulted (REFB is not used)
0 REFA fault Faults REFA input receiver
0 (default) = not faulted
1 = faulted (REFA is not used)
