6.6.1
SPM Write Sequence
The SPM must always be written in blocks of 8 bytes. The sequence is described below:
1. Set the I2C in SPM mode by writing “01” to SpmCfg[5:4] and SPM write access by writing ‘0’ to SpmCfg[3].
2. Write the SPM base address to SpmBaseAddr (The base address needs to be a value modulo 8).
3. Write the eight consecutive bytes to I2C address 0, 1, 2, …7
4. Terminate by writing “000” to SpmCfg[5:3].
Figure 58
SPM write sequence
The complete SPM can be written by repeating 16 times the cycles shown in Figure 58 using base addresses
0x00, 0x08, 0x10,…0x70, 0x78.
Once the SPM write sequence is actually applied, the INTB pin will be asserted. The host clears the interrupt by
reading any I2C register. At the same time the bit GenStatMsb[6], indicating the SPM write is done, will be
cleared.
