io8051.h.defines

Develop Zigbee network real-time Os

/*
 * These definitions must be turned into compiler specific register
 * definitions at a later point in the compile process (the mangle
 * script). For Keil the format is:
 *   sfr P0_dir at 0xFD
 *
 * This file defines properties shared among 8051 variants. Chip
 * specific additions are found in the directories for those chips
 *
 * The special function register definitions are created in a slightly
 * odd way in order to allow special attributes to pass through nescc
 * unchanged and then be modified by a mangle script later.
 *
 * The __attribute(()) will be removed by the mangle script and
 * the content x will be used to construct:
 *   sfr at x ...
 *
 * Alternative to stay within ANSI-C one could imagine using a
 * structure with bit fields say struct { int P0:1 }, however the
 * silly architecture of the 8051 forces us to controll whether code
 * using direct or indirect addressing is generated. I can't se how
 * this could be done using ANSI-C.
 *
 * The above scheme allows nescc to parse the code and sdcc to to
 * generate the appropriate code.
