Module Configuration
Resistive Drive
The specific configuration the CAT module is listed in the following tables.The module bus
clocks listed here are connected to the system bus clocks. Please refer to the Power Manager
chapter for details.
Table 28-4.
Table 28-5.
Table 28-6.
By default, the CAT pins are driven with normal I/O drive properties. Some of the CSA and CSB
pins can optionally drive with a 1k output resistance for improved EMC.
To enable resistive drive on a pin, the user must write a one to the corresponding bit in the CSA
Resistor Control Register (CSARES) or CSB Resistor Control Register (CSBRES) register.
