10.4.3 Send to CPU Settings
There are several RXP packet conditions that can be used to forward packets to the CPU that have been described
in previous Register Guide sections.

Register
G.ECCR1 - G.ECCR2
G.TCCR1 - G.TCCR2
The tables that follow provide most of the settings for T1/E1 and slower TDM Port applications. When a TDM Port
uses a Clock Recovery Engine there are some Clock Recovery Engine Registers that must be set that are not
identified in this section (e.g. selection between Adaptive Clock Recovery and Differential Clock Recovery). These
are defined by the S132 DSP Firmware load.
