Application description
=============================================
The XAG49IAPLIB is an In-Application Programming library for the XA-G49 Microcontroller which may be used with a C project. The library is implemented in assembler, but has a C interface hiding the assembler from the C programmer.

The package includes the library, a C header file, a manual in PDF format and an example project for the Raisonance XA Compiler.

The following functions are implemented in the library, giving access to all the features of IAP:

void iap_init(unsigned char frequency);
unsigned char iap_read_manufacturer_id(void);
unsigned char iap_read_device_id(unsigned char id_number);
unsigned char iap_read_security_bits(void);
unsigned char iap_read_data_byte(unsigned int addr);
unsigned int iap_read_boot_pc(void);
unsigned int iap_read_boot_psw(void);
unsigned char iap_read_status_byte(void);
unsigned char iap_erase_block(unsigned char block);
void iap_erase_chip(void);
unsigned char iap_program_data_byte(unsigned char val, unsigned int addr);
unsigned char iap_program_boot_pc(unsigned int boot_pc);
unsigned char iap_program_boot_psw(unsigned int boot_psw);
unsigned char iap_program_status_byte(unsigned char status_byte);
void iap_program_security_bits(unsigned char bits);
unsigned char iap_fill_block(unsigned char block);
unsigned char iap_erase_boot_psw(void);
unsigned char iap_erase_boot_pc(void);
unsigned char iap_erase_status_byte(void);
unsigned char iap_erase_chip_noreset(void);
