; 83C751 processor definition file; ================================;; Attention!; ----------; Philips has defined four BIT symbols in the I2STA; register that are leading to name conflicts:;; 1. Originally the same names have been assigned to the bits; XSTP, XSTR, and IDLE in the I2STA read-only register as; to the corresponding bits in the I2CON write register.; To make things unique, the bit symbols in the I2STA; register have been renamed to XSTP_, XSTR_, and IDLE_.;; 2. The XDATA bit symbol in the I2STA register is conflicting; with the XDATA keyword from the Intel MCS-51 assembly; language, and has therefore been abbreviated to XDAT.P0 DATA 080HSP DATA 081HDPL DATA 082HDPH DATA 083HPCON DATA 087HTCON DATA 088HTL DATA 08AHRTL DATA 08BHTH DATA 08CHRTH DATA 08DHP1 DATA 090HI2CON DATA 098HI2DAT DATA 099HIE DATA 0A8HP3 DATA 0B0HPSW DATA 0D0HI2CFG DATA 0D8HACC DATA 0E0HB DATA 0F0HI2STA DATA 0F8HSCL BIT 080HSDA BIT 081HIT1 BIT 088HIE1 BIT 089HIT0 BIT 08AHIE0 BIT 08BHTR BIT 08CHTF BIT 08DHCT BIT 08EHGATE BIT 08FHINT0 BIT 095HINT1 BIT 096HT0 BIT 097HXSTP BIT 098H ;writeMASTER BIT 099H ;readXSTR BIT 099H ;writeSTP BIT 09AH ;readCSTP BIT 09AH ;writeSTR BIT 09BH ;readCSTR BIT 09BH ;writeARL BIT 09CH ;readCARL BIT 09CH ;writeDRDY BIT 09DH ;readCDR BIT 09DH ;writeATN BIT 09EH ;readIDLE BIT 09EH ;writeRDAT BIT 09FH ;readCXA BIT 09FH ;writeEX0 BIT 0A8HET0 BIT 0A9HEX1 BIT 0AAHETI BIT 0ABHEI2 BIT 0ACHEA BIT 0AFHP BIT 0D0HOV BIT 0D2HRS0 BIT 0D3HRS1 BIT 0D4HF0 BIT 0D5HAC BIT 0D6HCY BIT 0D7HCT0 BIT 0D8HCT1 BIT 0D9HTIRUN BIT 0DCHCLRTI BIT 0DDHMASTRQ BIT 0DEHSLAVEN BIT 0DFHXSTP_ BIT 0F8HXSTR_ BIT 0F9HMAKSTP BIT 0FAHMAKSTR BIT 0FBHXACTV BIT 0FCHXDAT BIT 0FDHIDLE_ BIT 0FEHRESET CODE 000HEXTI0 CODE 003HTIMER0 CODE 00BHEXTI1 CODE 013HTIMER1 CODE 01BHI2CBUS CODE 023H⌨️ 快捷键说明
