Detailed Description

The tcDspBankSelect class is used to change the currently selected Flash bank.

In general, it should be created and passed to tcDspFlash for use internally. Access to Bank 0 of the device is blocked unless BOOTLOADER is defined in order to prevent accidental erase of the bootloader code (which could leave the board in an unusable state).
