Module Configuration
Clock Connections
The specific configuration for each Timer/Counter instance 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 24-4.
There are two Timer/Counter modules, TC0 and TC1, with three channels each, giving a total of
six Timer/Counter channels. Each Timer/Counter channel can independently select an internal
or external clock source for its counter:
