| * Macros for feature tests, used to enable include file features |
| * for chip features only present in certain chip revisions. |
| * |
| * SIBYTE_HDR_FEATURES may be defined to be the mask value chip/revision |
| * which is to be exposed by the headers. If undefined, it defaults to |
| * "all features." |
| * |
| * Use like: |
| * |
| * #define SIBYTE_HDR_FEATURES SIBYTE_HDR_FMASK_112x_PASS1 |
| * |
| * Generate defines only for that revision of chip. |
| * |
| * #if SIBYTE_HDR_FEATURE(chip,pass) |
| * |
| * True if header features for that revision or later of |
| * that particular chip type are enabled in SIBYTE_HDR_FEATURES. |
| * (Use this to bracket #defines for features present in a given |
| * revision and later.) |
| * |
| * Note that there is no implied ordering between chip types. |
| * |
| * Note also that 'chip' and 'pass' must textually exactly |
| * match the defines below. So, for example, |
| * SIBYTE_HDR_FEATURE(112x, PASS1) is OK, but |
| * SIBYTE_HDR_FEATURE(1120, pass1) is not (for two reasons). |
| * |
| * #if SIBYTE_HDR_FEATURE_UP_TO(chip,pass) |
| * |
| * Same as SIBYTE_HDR_FEATURE, but true for the named revision |
| * and earlier revisions of the named chip type. |
| * |
| * #if SIBYTE_HDR_FEATURE_EXACT(chip,pass) |
| * |
| * Same as SIBYTE_HDR_FEATURE, but only true for the named |
| * revision of the named chip type. (Note that this CANNOT |
| * be used to verify that you're compiling only for that |
| * particular chip/revision. It will be true any time this |
| * chip/revision is included in SIBYTE_HDR_FEATURES.) |
| * |
| * #if SIBYTE_HDR_FEATURE_CHIP(chip) |
| * |
| * True if header features for (any revision of) that chip type |
| * are enabled in SIBYTE_HDR_FEATURES. (Use this to bracket |
| * #defines for features specific to a given chip type.) |
| * |
| * Mask values currently include room for additional revisions of each |
| * chip type, but can be renumbered at will. Note that they MUST fit |
| * into 31 bits and may not include C type constructs, for safe use in |
| * CPP conditionals. Bit positions within chip types DO indicate |
| * ordering, so be careful when adding support for new minor revs. |

| * Naming schemes for constants in these files: |
| * |
| * M_xxx MASK constant (identifies bits in a register). |
| * For multi-bit fields, all bits in the field will |
| * be set. |
| * |
| * K_xxx "Code" constant (value for data in a multi-bit |
| * field). The value is right justified. |
| * |
| * V_xxx "Value" constant. This is the same as the |
| * corresponding "K_xxx" constant, except it is |
| * shifted to the correct position in the register. |
| * |
| * S_xxx SHIFT constant. This is the number of bits that |
| * a field value (code) needs to be shifted |
| * (towards the left) to put the value in the right |
| * position for the register. |
| * |
| * A_xxx ADDRESS constant. This will be a physical |
| * address. Use the PHYS_TO_K1 macro to generate |
| * a K1SEG address. |
| * |
| * R_xxx RELATIVE offset constant. This is an offset from |
| * an A_xxx constant (usually the first register in |
| * a group). |
| * |
| * G_xxx(X) GET value. This macro obtains a multi-bit field |
| * from a register, masks it, and shifts it to |
| * the bottom of the register (retrieving a K_xxx |
| * value, for example). |
| * |
| * V_xxx(X) VALUE. This macro computes the value of a |
| * K_xxx constant shifted to the correct position |
| * in the register. |
