;   ================================
;
;   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.
