void initAllPagedAddresses | ( | ) |
Buffer addresses of paged data.
If you try to access paged data from the wrong place you get nasty warnings. These calls to functions that live in the same page that they are addressing prevent those warnings.

void initAllPagedRAM | ( | ) |
Copies paged flash to RAM.
Take the tables and config from flash up to RAM to allow live tuning.
For the main tables and other paged config we need to adjust the RPAGE value to the appropriate one before copying up.
This function is simply a delegator to the ones for each flash page. Each one lives in the same paged space as the data it is copying up.

void initFlash | ( | ) |
Flash module setup.
Initialise configuration registers for the flash module to allow burning of non-volatile flash memory from within the firmware.
The FCLKDIV register can be written once only after reset, thus the lower seven bits and the PRDIV8 bit must be set at the same time.
We want to put the flash clock as high as possible between 150kHz and 200kHz
The oscillator clock is 16MHz and because that is above 12.8MHz we will set the PRDIV8 bit to further divide by 8 bits as per the manual.
16MHz = 16000KHz which pre-divided by 8 is 2000kHz
2000kHz / 200kHz = 10 thus we want to set the divide register to 10 or 0x0A
Combining 0x0A with PRDIV8 gives us 0x4A (0x0A | 0x40 = 0x4A) so we use that
