- Note: You can usually deduce the serial number of the system controller chip on the motherboard when knowing Baryon version. For example, 0x00030600 has the BAR14 labelled chip, while 0x00040600 has the BAR15 labelled chip.

Notes[edit | edit source]
Note 2.
The parity calculation for the END field is performed as follows (when the last address is 005FFFH)
<1> The END field is divided in 7-bit units from the lower digit (the higher 3 bits are discarded).
0 0 5 F F F 00000000 01011111 11111111 ↓ 000 0000001 0111111 1111111
<2> The odd parity bit is appended to the highest bit.
p0000001 p01111111 p1111111 (p = odd parity bit) = 0000001 10111111 01111111 = 01 BF 7F
<3> The order of the higher, middle, and lower bytes is reversed, as follows. 7F BF 01
CHAPTER 5 DESCRIPTION OF COMMAND PROCESSING
Application Note U17739EJ2V0AN 50
The following shows the procedure to translate the values in the END field that has been sent from the microcontroller to the actual address.
<1> The order of the higher, middle, and lower bytes is reversed, as follows.
7F BF 01 ↓ 01 BF 7F
<2> Checks that the number of “1” is odd in each byte (this can be performed at another timing).
<3> The parity bit is removed and a 3-bit 0 is added to the highest bit.
01 BF 7F ↓ 00000001 10111111 01111111 ↓ 0000001 0111111 1111111 ↓ 000 0000001 0111111 1111111
<4> The values are translated into groups in 8-bit units.
00000000101111111111111 ↓ 00000000 01011111 11111111 ↓ = 0 0 5 F F F
If “7F BF 01” is given to the END field, the actual last address is consequently 005FFFH.
Note 3. When security flag information is set using the Security Set command, the highest bit is fixed to “1”. If the security flag information is read using the Silicon Signature command, however, the highest bit is the odd parity.
