26.2. C2 Pin Sharing
The C2 protocol allows the C2 pins to be shared with user functions so that in-system debugging and
Flash programming functions may be performed. This is possible because C2 communication is typically
performed when the device is in the halt state, where all on-chip peripherals and user software are stalled.
In this halted state, the C2 interface can safely ‘borrow’ the C2CK (/RST) and C2D (P2.0) pins. In most
applications, external resistors are required to isolate C2 interface traffic from the user application. A typi-
cal isolation configuration is shown in Figure 26.1.
The configuration in Figure 26.1 assumes the following:
Additional resistors may be necessary depending on the specific application.
1. The user input (b) cannot change state while the target device is halted.
2. The /RST pin on the target device is used as an input only.
