7.2 Emulator Support for TrustZone
Renesas provides an emulator which supports both debugging using SWD or JTAG communication and
serial programming using SCI communication. This emulator makes it easy to switch between debugging
and serial programming. The following table shows the pinout of a 10-pin or 20-pin socket when using this
emulator. The pinout of SWD and JTAG is Arm
®
standard, and MD, TXD, and RXD pins are added for the
serial programming using SCI communication.
The serial programming interface must be used to program the TrustZone IDAU boundary register settings. It
is recommended to connect P300/SWCLK/TCK and P201/MD pins using wired OR circuit on the board to
use both debugging and serial programming.
