Product information (such as product name and firmware version) can be obtained by executing the “Silicon Signature”
command.
Table 26-8 is a list of signature data and Table 26-9 shows an example of signature data.
Table 26-8. Signature Data List
Field name Description Number of transmit data
Device code The serial number assigned to the device 3 bytes
Device name Device name (ASCII code) 10 bytes
Code flash memory area last address Last address of code flash memory area
(Sent from lower address.
Example: 00000H to 0FFFFH (64 KB) → FFH, FFH, 00H)
3 bytes
Data flash memory area last address Last address of data flash memory area
(Sent from lower address.
Example: F1000H to F1FFFH (4 KB) → FFH, 1FH, 0FH)
3 bytes
Firmware version Version information of firmware for programming
(Sent from upper address.
Example: From Ver. 1.23 → 01H, 02H, 03H)
