Renesas Single-Chip Microcomputer H8/36079 - Manual (Page 18)

Chapter 7. Modes
This RSK supports Boot mode and User mode.
Details of programming the FLASH memory is described in the H8/38347 Group Hardware Manual.
7.1. Boot mode
The boot mode settings for this RSK are shown in Table 7-1: Boot Mode pin settings below:
TEST NMI P85 LSI State after Reset End
0 Low High Boot Mode
Table 7-1: Boot Mode pin settings
The software supplied with this RSK supports Boot mode using an E8A and HEW only. However, hardware exists to enter boot mode
manually, do not connect the E8A in this case. Press and hold the SW1/BOOT. The pin NMI (microcontroller pin 35) is held in its boot state
while reset is pressed and released. Release the boot button. The BOOT LED will be illuminated to indicate that the microcontroller is in
boot mode.
When neither the E8A is connected nor the board is placed in boot mode as above, the TEST pin is connected to Ground; the NMI pin is
pulled high by a 10k resistor, the P8.5 pin is pulled high with a 4.7k resistor.
When an E8A is used the port P85 and NMI are controlled by the E8A.
7.2. User mode
Because the NMI pin is pulled high, this RSK will always boot in User mode when the E8A is not connected and the boot switch is not
depressed. Refer to H8/36079 Group Hardware Manual for details of User mode. The user mode settings for this RSK are shown in Table
7-1: Boot Mode pin settings below:
TEST NMI P85 LSI State after Reset End
0 High X User Mode
X: Don’t care
