3.5.7 A/D Converter

The A/D converter has AVcc, AVss, Avref, and _ADTRG pins as well as the analog input pins. As the A/D

converter operates with an independent power supply, connect AVcc (the power supply pin) to the A/D power

supply on the user system.

Notes: 1. When not using the A/D converter, connect AVcc to Vcc.

2. As the user system interface cable, printed circuit boards, and protective circuits are connected

between the MCU and the user system in the emulator pod, the conversion precision is lower than

that of the SH7046 series or SH7144 series MCUs. At final debugging of the user system using the

A/D converter, use the actual SH7046 series or SH7144 series (F-ZTAT microcomputer) MCUs.

3.5.8 Emulator State and On-Chip Modules

Some on-chip modules do not operate when the emulator is in break mode. Table 3.7 shows the relation between

the emulator’s state and operation of the on-chip modules.

Table 3.7 Emulator State and Operation of On-Chip Modules

On-Chip Module

Operation During

Emulation Halted

(Break)

Operation During

Emulation

(Execution or Step

Execution)

WDT (watchdog timer) No Yes

MTU (multi-function timer pulse unit) Yes Yes

MMT (motor management unit) Yes Yes

CMT (compare-match timer) Yes Yes

SCI (serial communication interface) Yes Yes

DTC (data transfer controller) Yes

Yes

HCAN2 Yes Yes

UBC (user break controller) No Yes

AUD (advanced user debugger) Yes Yes

I/O port Yes Yes

A/D converter Yes Yes

H-UDI (user debugging interface) Not available

Not available

Notes: 1. If a break occurs during a DTC cycle (vector read, read/write of transferred information, or data

read/write), the DTC continues operation until the DTC cycle is complete. The DTC resumes

operation after it returns to emulation.

2. Not supported by the emulator.
