Application description
=============================================
Keil specific files have their names prefixed with 'k'.

The 669IAPLIB is an In-Application Programming library for the P89C669 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 both the Keil 8051 Compiler.

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

unsigned char iap_read_manufacturer_id(void);
unsigned char iap_read_device_id(unsigned char id_number);
unsigned char iap_read_security_bits(void);
void iap_program_security_bits(unsigned char bits);
unsigned char iap_program_data_byte(unsigned char val, unsigned int addr, unsigned char seg);
unsigned char iap_read_data_byte(unsigned int addr, unsigned char seg);
unsigned char iap_erase_block(unsigned int block);
unsigned int iap_read_boot_vector(void);
unsigned char iap_read_status_byte(void);
unsigned char iap_erase_bv_sb(void);
unsigned char iap_program_status_byte(unsigned char status_byte);
unsigned char iap_program_boot_vector(unsigned int boot_vector);
