(1) TVcc Threshold [FUNC D3]
Set up a value about 10% lower than the minimum operation voltage of the target
microcomputer.
NET IMPRESS senses the operation voltage (TVcc) of the target microcomputer and executes
the Device Functions when the TVcc gets higher than the specified value.
For the operation procedure to set up TVcc threshold on NET IMPRESS main unit, see the
NET IMPRESS next Instruction Manual at section 5. 4. 5 “TVcc Threshold Setting”.
(2) Flash ROM (First Address, Last Address) [FUNC D6]
Set up the flash memory area (First Address, Last Address) embedded in the microcomputer.
You cannot set up Flash ROM area for NET IMPRESS with key operation (FUNC D6), which
only displays it.
For details, see the NETIMPRESS next instruction Manual at Section 5. 4. 8 “Flash Memory
Area Display”.
(3) ROM Block Configuration
Set up the block configuration of flash memory.
<Block Data Table>
The block data table consists of three kinds of information: Group No., Start Address and Block
Size.
Group No.:
You can specify up to 14 groups (Group1 to Group 14).
A block group consists of memory blocks that have the same one block size
on linear address. Group number is determined by the address order starting
from lower address.
Start Address:
A start address of a block group.
Block of the size specified in the Block Size sequentially continues, forming
one block group.
Block Size:
NET IMPRESS understands that the blocks of a size specified in the Block
Size are placed sequentially until a next block group address.
When the Block Size is set at 1, the block is designated as access forbidden
area. Programming or Erasing is not executed in Access forbidden area even
the area is located within the area to execute the device functions.
