90:C:/WinAVR/avr/include/avr/eeprom.h **** This header file declares the interface to some simple library
91:C:/WinAVR/avr/include/avr/eeprom.h **** routines suitable for handling the data EEPROM contained in the
92:C:/WinAVR/avr/include/avr/eeprom.h **** AVR microcontrollers. The implementation uses a simple polled
93:C:/WinAVR/avr/include/avr/eeprom.h **** mode interface. Applications that require interrupt-controlled
94:C:/WinAVR/avr/include/avr/eeprom.h **** EEPROM access to ensure that no time will be wasted in spinloops
95:C:/WinAVR/avr/include/avr/eeprom.h **** will have to deploy their own implementation.
96:C:/WinAVR/avr/include/avr/eeprom.h ****
97:C:/WinAVR/avr/include/avr/eeprom.h **** \note All of the read/write functions first make sure the EEPROM
98:C:/WinAVR/avr/include/avr/eeprom.h **** is ready to be accessed. Since this may cause long delays if a
99:C:/WinAVR/avr/include/avr/eeprom.h **** write operation is still pending, time-critical applications
100:C:/WinAVR/avr/include/avr/eeprom.h **** should first poll the EEPROM e. g. using eeprom_is_ready() before
101:C:/WinAVR/avr/include/avr/eeprom.h **** attempting any actual I/O.
102:C:/WinAVR/avr/include/avr/eeprom.h ****
103:C:/WinAVR/avr/include/avr/eeprom.h **** \note This header file declares inline functions that call the
104:C:/WinAVR/avr/include/avr/eeprom.h **** assembler subroutines directly. This prevents that the compiler
105:C:/WinAVR/avr/include/avr/eeprom.h **** generates push/pops for the call-clobbered registers. This way
106:C:/WinAVR/avr/include/avr/eeprom.h **** also a specific calling convention could be used for the eeprom
107:C:/WinAVR/avr/include/avr/eeprom.h **** routines e.g. by passing values in __tmp_reg__, eeprom addresses in
108:C:/WinAVR/avr/include/avr/eeprom.h **** X and memory addresses in Z registers. Method is optimized for code
109:C:/WinAVR/avr/include/avr/eeprom.h **** size.
110:C:/WinAVR/avr/include/avr/eeprom.h ****
111:C:/WinAVR/avr/include/avr/eeprom.h **** \note Presently supported are two locations of the EEPROM register
112:C:/WinAVR/avr/include/avr/eeprom.h **** set: 0x1F,0x20,0x21 and 0x1C,0x1D,0x1E
113:C:/WinAVR/avr/include/avr/eeprom.h **** (see ::__EEPROM_REG_LOCATIONS__).
114:C:/WinAVR/avr/include/avr/eeprom.h ****
115:C:/WinAVR/avr/include/avr/eeprom.h **** \note As these functions modify IO registers, they are known to be
116:C:/WinAVR/avr/include/avr/eeprom.h **** non-reentrant. If any of these functions are used from both,
117:C:/WinAVR/avr/include/avr/eeprom.h **** standard and interrupt context, the applications must ensure
118:C:/WinAVR/avr/include/avr/eeprom.h **** proper protection (e.g. by disabling interrupts before accessing
