Table 26-130. GTU Configuration Register 11 (GTUC11) Field Descriptions
Bit Field Value Description
31-27 Reserved 0 Read returns 0. Writes have no effect.
26-24 ERC 0-7h µT External rate correction (in microticks). Holds the external clock rate correction value to be applied
by the internal clock synchronization algorithm. The value is subtracted/added from/to the
calculated rate correction value. The value is applied during NIT. May be modified in
DEFAULT_CONFIG or CONFIG state only.
23-19 Reserved 0 Read returns 0. Writes have no effect.
18-16 EOC 0-7h µT External offset correction (in microticks). Holds the external clock offset correction value to be
applied by the internal clock synchronization algorithm. The value is subtracted/added from/to the
calculated offset correction value. The value is applied during NIT. May be modified in
DEFAULT_CONFIG or CONFIG state only.
15-10 Reserved 0 Read returns 0. Writes have no effect.
9-8 ERCC External rate correction control. By writing to ERCC, the external rate correction is enabled as
specified below. Should be modified only outside NIT.
0, 1h No external rate correction
2h External rate correction value subtracted from calculated rate correction value
3h External rate correction value added to calculated rate correction value
7-2 Reserved 0 Read returns 0. Writes have no effect.
1-0 EOCC External offset correction control. By writing to EOCC, the external offset correction is enabled as
specified below. Should be modified only outside NIT.
0-1h No external offset correction
2h External offset correction value subtracted from calculated offset correction value
3h External offset correction value added to calculated offset correction value
