Register Bit not available
and not needed any longer
Differences compared to SDA 525x according to preliminary specification 06/96:
1. The serial interface is not supported any longer. By this, registers SCON and SBUF
are no longer available. The “Serial Interrupt Enable Flag” ES of the Interrupt Enable
register (Bit 4 of A8) must not be written (default after reset = 0).
2. The functions and bits Prescaler Control (PSC) and ADC sample time (STADC) of the
Special Function Register ADCON are not available any more. Bits 7 and 6 of D8 must
be 0.
3. The registers following must not be written. The software needs to be checked
accordingly.
SBUF (99):
Bits 0 to 7
SCON (98):
Bits 0 to 7
ACQMS2 (C2): Bits 0 to 7
DMODE2 (C7): Bits 5 to 7
ADCON (D8):
Bits 6 and 7
IE (A8):
Bit 4
The allowed bits of DMODE2, ADCON and IE have to be changed with the commands
ANL or ORL.
