2.4.4 8-bit LEDs on the Debug Board
The low-order 8 bits (D7 to D0) of the SH7727 data bus are connected to the 8-bit LEDs placed on the debug
board. The 8-bit LEDs can be turned on or off by writing data to an area assigned for the LEDs through D7 to
D0. When a value of 1 is written to a bit, the corresponding LED is turned off. When a value of 0 is written
to the bit, it is turned on. The 8-bit LED area is common to the EPROM area. When writing takes place,
LED access takes place. When reading takes place for this area, EPROM access takes place. Note that
LED access must take place in words to enable the lower 8 bits (D7 to D0).
2.4.5 OCD emulator Connection
The debug board allows the OCD emulator to be connected to the 36-pin (CN2) connector. Connect the H-
UDI and AUD pins of the SH7727 board to the CN2. Figure 2.6 shows a method for connecting the OCD
emulator. Connect an OCD emulator cable to the CN2 of the debug board. Note that the following OCD
emulator can be connected to T-Engine. For details on the OCD emulator connection/setup procedure, refer
to the pertinent manual of the product.
