< Notes in case M3A-0029B is connected >
The power supply to M3A-0033 and M3A-0032, “External power supply (CN1)” or “ Vbus power supply on USB
line” are selectable. Please set up the jumper as Table 6-1.
Table 6-1 Jumper Setting for Supplying Origin of External Power Supply
Note: Please be sure to observe the correct polarity, since this board has no reserve polarity protection.
And, the supply voltage to V
Please set up the jumper as shown in Table 6-2.
Table 6-2 Jumper Setting for Supplying Voltage to IOVCC of M16C/80, M66291GP
- 3.3V is supplied to CoreV
- User should set JP1 of M3A-0032 to “EXIOVCC” side.
Note: Vbus power is then supplied when Vbus is selected as the origin of external power supply.
Table 6-3 shows the supply voltage by the combination of JP5 and JP6 setup.
Table 6-3 Supply voltage by combination of JP5 and JP6
In case M3A-0029B is connected, please be sure to set JP5 to “EX5V” side, JP6 to “3.3V” side.
If it sets up other than the above, M3A-0029B does not operate. Moreover, the worst case, M66290AGP may be
destroyed.
Setting as shown in Table 6-6, *DREQ0 pin and *DREQ1 pin of M66291GP are assigned to *INT1 pin and *INT2
pin of M16C/80 respectively, and DMA transfer can be performed by handshake.
Table 6-4 Jumper Setting of *DREQ0 DMA Transfer
<Notes in case M3A-0029B is connected>
- Since the M66290 needs *Dack for DMA transfer, please short-circuit JP17 (When JP17 is short-circuited, *Dack
pin of M66290A and *CS2 pin of M16C/80 will be connected and JP9 will be invalid).
