COMMON OPERATIONAL CONTROLS (REGISTER 0x0A00 TO REGISTER 0x0A0E)

Table 145. Global Operational Controls

Address

Bits

Bit Name

Description

0x0A00

[7:3]

Reserved

Default: 00000b.

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.

Calibrate all

Calibrates both output PLL0 (APLL_0) and output PLL1 (APLL_1).

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

REFD power-down

Powers down REFD input receiver

0 (default) = not powered down

1 = powered down

REFC power-down

Powers down REFC input receiver

0 (default) = not powered down

1 = powered down

REFB power-down

Powers down REFB input receiver

0 (default) = not powered down

1 = powered down

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

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).

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).

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).

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).

Bit Name

Description

0x0A03

[7:4]

Reserved

Default: 0x0

REFD fault

Faults REFD input receiver

0 (default) = not faulted

1 = faulted (REFD is not used)

REFC fault

Faults REFC input receiver

0 (default) = not faulted

1 = faulted (REFC is not used)

REFB fault

Faults REFB input receiver

0 (default) = not faulted

1 = faulted (REFB is not used)

REFA fault

Faults REFA input receiver

0 (default) = not faulted

1 = faulted (REFA is not used)
