Question:

How do I put my H8 300SLP device into boot mode ?

Answer:

To put the device into boot mode you should follow the instructions given in the ROM section of the Hardware manual. The example below shows how to boot the H8/38024F: TEST0 - Low Level.; Port 9.50 - Low Level ; Port 3.41 - High Level.Once these conditions have been met apply a reset as per the device specification. The device will then be in Boot Mode. Boot mode can be cleared by a reset. End the reset after driving the reset pin low waiting at least 20 states and then setting the TEST pin and P95 pin. Boot mode is also cleared when a WDT overflow occurs. Do not change the TEST pin and P95 pin input levels in boot mode.
