JTAG/Trace Pins

The following figures show examples when this LSI chip is connected to the ICE (in-circuit emulator).
They are examples when connected to the 20-pin half-pitch connecter or 20-pin full-pitch connecter of standard.
R-IN32M3
RESETZ
HOTRE SETZ
TRS TZ
JTA GSEL
HOTRE SETZ is i nco rporated
only in the R-IN32M3-CL.

As long as nRESET is input to RESETZ, nRESET is not required to input to HOTRESETZ.
RESETZ resets the entire LSI, but the internal PLL is not reset in the case of only HOTRESETZ. Please use it to meet
your needs.
In addition, nRESET should not be connected to PONRZ.
