The pin numbers and corresponding signals of the user system interface cable used for connecting the adapter board and

user system are shown below.

Table 4-1 Pin Numbers and Corresponding Signals of the HS0008EAUF1H User Interface Cable

No Signal Name No. Signal Name

1 RES 2 GND

3 FWx 4 GND

5 MD0 6 GND

7 MD1 8 GND

9 MD2 (IO0) 10 GND

11 MD3 (IO1) 12 GND

13 MD4 (IO2) 14 GND

15 RXD (TXD on the user system side) 16 GND*1

17 TXD (RXD on the user system side) 18 VIN (Vcc or PVcc)*2

19 SCK (NC) 20 VIN (PVcc)*2

Notes:

1. Be sure to connect pin No. 16 to GND to confirm that the user system is connected properly.

2. For a device with Vcc and PVcc, be sure to supply Vcc or PVcc (pin No. 18) and PVcc (pin No. 20) to the VIN pins of

the user interface connector, respectively. To use a device under condition that Vcc = PVcc, or only Vcc is present in the

device, be sure to supply Vcc to both VIN pins Vcc or PVcc (pin No. 18) and PVcc (pin No. 20).

Connecting the Adapter Board

An example of connecting the H8S/2378F and Renesas adapter board (HS0008EAUF1H) is shown in

Figure 4-2. The

pull-up and pull-down resistor values shown are only examples. Evaluate the microcomputer to determine the actual

values on the user system.
