Hi,
I wrote this function to inizialize the i2c0 devices but i think that is not correct init function because the i2c interrupt is not activeted.

How does one effectively use P0.14 (SDA) if it is also used to select
bootload? Surely the necessary pull-up required to make the I2C line
work also forces bootload mode?

It seems as though all registers for SPI can't be accessed or set unless
SPI bit is turned on in PCONP. However, that doesn't seem to be the
case for I2C.

It would make sense to use small size memory for cost concerns. So even using a 32Kb memory, that has a page size of 32 bytes (Microchip 24AA32A) will need 8 iteratio...
