3.5 About M3T-PD32RM
The following describes precautions to be observed when using M3T-PD32RM.
3.5.1 Operating Manuals
To use M3T-PD32RM of M3A-2114G52A/ G62A/ G72A, see the manuals shown below.
To use M3S-KD32R of M3A-2114G52/ G62/ G72, see the manuals shown below.
3.5.2 About Break Operation
M3T-PD32RM (or M3S-KD32R) uses the M32R core’s internal debug circuit (SDI) to realize break functions. For this
reason, the break functions of M3T-PD32RM (or M3S-KD32R) behave differently from those in conventional emulators.
Furthermore, because M3T-PD32RM (or M3S-KD32R) does not have SDI trace pins as corresponding hardware
resources, the trace pin corresponding break functions available with M3T-PD32R-compatible emulators are not
supported.
The following explains the four types of breaks that can be executed with M3T-PD32RM (or M3S-KD32R).
(1) Software break
(2) Pre-execution PC break
(3) Post-execution PC break
(4) Chip break
MCU), four such breakpoints can be set.

Up to 64 software breakpoints can be set and executed in RAM areas accessible by the target MCU. No software
breakpoints can be set and executed in ROM areas such as the internal flash memory.
The M32R core’s internal debug circuit (SDI) allows setting breakpoints, at which to break the program immediately
before executing an instruction (at the address indicated by the program counter).
For the M3A-2114G52A/ G62A/ G72A and M3A-2114G52/ G62/ G72 (32170/32171/32172/32173/32174 group
The M32R core’s internal debug circuit (SDI) allows setting one breakpoint, at which to break the program
immediately after executing an instruction (at the address indicated by the program counter).
The M32R core’s internal debug circuit (SDI) allows setting breakpoints, at which to break the program when
accessing memory for read/write.
For M3A-2114G52A/ G62A/ G72A and M3A-2114G52/ G62/ G72 (32170/32171/32172/32173/32174 group MCU),
two such breakpoints (level 2) can be set.
* The differences between levels 1 and 2 are outlined below.
Level 1: Whether data which is maskable matches or not can be detected.
Level 2: Data is maskable and an address range can be specified for the target data.
