mode.
10.1 ISP Command Write
The 2nd byte of “Command Write” can define the operating mode of MTV230M in its “Data write” stage,
clear CRC register, or reset MTV230M. The bit 0 of 2
0=Code). The 3rd byte of Command Write defines the page address (A15-8 of Code Flash, A13-7 of OSD
Flash). A Command Write may consist of 1,2 or 3 bytes.

10.3 ISP Data Write
The 2
MTV230M will execute a Program/Erase/Blank command depending on the preceding “Command Write”. If
Code area is selected, the low address of Code Flash will increase every time when ISP slave acknowledges
the data byte. If OSD Flash is selected, the low address of OSD Flash will increase when every 2 data bytes
are received. The Blank/Erase command needs one data byte (content is “don’ t care”). The executing time is
10mS. During the 10mS period, the ISP slave does not accept any command/data and returns non-ack to
any IIC bus activity. The Program command may have 1-256 data bytes for Code Flash, and have 1-128
word(256 bytes) for OSD Flash. The program cycle time is 60us. If the ISP slave is not able to complete the
program cycle in time, it will return non-ack to the following data byte. In the meantime, the low address does
not increase and the CRC does not count the non-acked data byte. A Data Write may consist of 1,2 or more
bytes.
