26.6.3 Unlock (C_CAN ISP)
Write <Unlock Code> to [0x5000, 0]. Writing an invalid unlock code will return a dedicated
abort code.
26.6.4 Write to RAM (C_CAN ISP)
Set RAM write address by writing to [0x5015, 0]. Then write the binary data to [0x1F50, 1].
Since this is a DOMAIN entry, the data can be continuously written. The host terminates
the write. The write address in [0x5015, 0] auto-increments, so a write of a larger area
may be done in multiple successive write cycles to [0x1F50, 1].
26.6.5 Read memory (C_CAN ISP)
Set RAM read address by writing to [0x5010, 0] and the read length by writing to
[0x5011,0]. Then read the binary data from [0x1F50,1]. Since this is a DOMAIN entry, the
data is continuously read. The device terminates the read when the number of bytes in the
read length entry has been read. The read address in [0x5010, 0] auto-increments, so a
read of a larger area may be done in multiple successive read cycles from [0x1F50,1].
26.6.6 Prepare sectors for write operation (C_CAN ISP)
Write a 16-bit value to [0x5020, 0] with the start sector number in the lower eight bits and
the end sector number in the upper eight bits.
26.6.7 Copy RAM to flash (C_CAN ISP)
Write the parameters into entry [0x5050, 1 to 3]. The write of the number of bytes into
[0x5050,3] starts the programming.
