Table 17-6 Transfer Format for the RAM Transfer Command
Byte Data Transferred from the Controller
to the TMPM330
Boot ROM 1 byte Serial operation mode and baud rate
For UART mode 86H
For I/O Interface mode 30H
TMPM330 (rev 0.4)17-19
TMPM330
Baud rate Data Transferred from the TMPM330
to the Controller
Desired baud
rate (Note 1)
2 byte - ACK for the serial operation mode byte
For UART mode
-Normal acknowledge 86H
(The boot program aborts if the baud rate
can not be set correctly.)
For I/O Interface mode
-Normal acknowledge 30H
3 byte Command code (10H) -
4 byte - ACK for the command code byte (Note 2)
-Normal acknowledge 10H
-Negative acknowledge × 1H
-Communication error × 8H
5 byte - Password sequence (12 bytes)
-
16 byte (0x3F8F_FFF4∼0x3F8F_FFFF)
17 byte Check SUM value for bytes 5 - 16 -
18 byte - ACK for the checksum byte (Note 2)
-Normal acknowledge 10H
-Negative acknowledge x1H
-Communication error x8H
19 byte RAM storage start address 31 - 24 -
20 byte RAM storage start address 23 - 16 -
21 byte RAM storage start address 15 - 8 -
22 byte RAM storage start address 7 - 0 -
23 byte RAM storage byte count 15 - 8 -
24 byte RAM storage byte count 7 - 0 -
25 byte Check SUM value for bytes 19 - 24 -
26 byte - ACK for the checksum byte (Note 2)
-Normal acknowledge 10H
-Negative acknowledge x1H
-Communication error x8H
27 byte
∼
m byte
RAM storage data -
m + byte Checksum value for bytes 27 - m -
m + byte - ACK for the checksum byte (Note 2)
-Normal acknowledge 10H
-Negative acknowledge x1H
-Communication error x8H
RAM m + byte - Jump to RAM storage start address
(Note 1) In I/O Interface mode, the baud rate for the transfers of the first and second bytes must be
1/16 of the desired baud rate.
(Note 2) In case of any negative acknowledge, the boot program returns to a state in which it waits
for a command code (3rd byte). In I/O Interface mode, if a communication error occurs, a
negative acknowledge does not occur.
(Note 3) The 19th to 25th bytes must be within the RAM address range 0x2000_0400∼0x2000_7FFF.
