|
33 // - General-purpose I/O allocation such as |

34 // #define KtVariantGpio32KHzClkOut KHtGpioPort1 |
|
35 // #define KtVariantGpioRClkOut KHtGpioPort0 |
|
36 // |
|
37 // #define KmVariantPinDirectionIn Sleep 0 |
|
38 // |
|
39 // - Memory constants (type, geometry, wait states, etc) such as: |
|
40 // #define KwVariantRom0Type TTemplate::ERomTypeBurst4Rom |
|
41 // #define KwVariantRom0Width TTemplate::ERomWidth32 |
|
42 // const TUint KwVariantRom0WaitNs = 150; |

43 // const TUint KwVariantRom0PageNs = 30; |
|
44 // const TUint KwVariantRom0RecoverNs = 55; |
|
45 // |
|
46 // - Specific Peripherals (Keyboard, LCD, CODECS, Serial Ports) such as |
|
47 // const TUint KwVariantKeyColLshift = 7; |
|
48 // #define KwVariantLcdBpp TTemplate::ELcd8BitsPerPixel |
|
49 // const TUint KwVariantLcdMaxColors = 4096; |
|
50 // const TUint KwVariantCodecMaxVolume = 0; |
|
51 // |
|
52 // - Off-chip hardware control blocks (addresses, register make-up) |
|
53 // |
|
54 // - Interrupts (second-level Interrupt controller base address, register make-up): |
|
55 // (EXAMPLE ONLY:) |
