4.11 C33 Debugger Port
The S2D13515 contains an embedded C33 microprocessor core. The debug monitor interface is available on
connector H2 for firmware debugging using C33 Debugger. In order to use connector H2, zero ohm resistors must
be configured depending on the desired S2D13515 configuration.
The C33 debugger function can be sourced from 2 sets of the host interface pins or from a set of FP2IO pins.
Figure 4-9: C33 Debugger Zero Ohm Resistor Overview Diagram
The connection to the C33 Debugger port is determined by populating the correct set of zero ohm resistors as
described below.
S5U13515P00C100 board comes configured for the C33 Debugger port from the Host Interface AB[11:6] pins, so
resistors R63, R65 ~ R69 are populated and R197 ~ R202 are not populated, R203 ~ R215 are populated and R64,
R70 ~ R81 are not populated.
