On-Chip Debug Enable
Serial Interface
Caution:
The DBG pin is mainly used for debugging. The OCD is always enabled by default fol-
lowing reset. Disable the OCD after startup and use the DBG pin as a UART or a GPIO
pin if the
To use the DBG pin as a UART or GPIO pin, the OCD must be disabled. The OCD is dis-
abled by clearing the OCDEN bit in the Debug Control Register (DBGCTL). The OCD
cannot be disabled, if the OCDLOCK bit in the DBGCTL register is set.
The DBG pin is used for serial communication. This one-pin interface is a bidirectional
half-duplex open-drain interface that transmits and receives data. Transmit and receive
operations cannot occur simultaneously. The serial data is sent and received using the
asynchronous protocol defined in RS–232. The serial pin is connected to the serial port of
the PC using minimal external hardware. Two different methods for connecting the serial
pin to an RS-232 interface are depicted in Figures 51 and 52.
The serial pin is open-drain and must be connected to V
resistor to ensure proper operation.
For effective operation of the device, all power pins (V
supplied with power and all ground pins (V
grounded. The DBG pin must be connected to V
resistor to ensure proper operation.
