2.1.3 Port Driver Circuitries
The port structures of the MYMOS and ACMOS versions are functionally compatible. For low power
consumption the pullup arrangement is realized differently in both versions.
Chapters 7.1.1.1, 7.1.1.2, 7.1.1.3 are dealing with the port structures in detail.
2.1.4 The A/D Converter Input Ports
The analog input ports (AN0 to AN7) of the SAB 80515/80535 can only be used as analog inputs
for the A/D converter.
The analog input ports (P6.0 to P6.7) of the SAB 80C515/80C535 can be used either as input
channels for the A/D converter or as digital inputs (see chapter 7.4)

Function
When set, the baud rate of the serial channel in mode 1, 2, 3 is doubled.
Power-down start bit. The instruction that sets the PDS flag bit is the last
instruction before entering the power-down mode.
Idle start bit. The instruction that sets the IDLS flag bit is the last instruction
before entering the idle mode.
Reserved
General purpose flag
General purpose flag
Power-down enable bit. When set, starting of the power-down mode is
enabled.
Idle mode enable bit. When set, starting of the idle mode is enabled.
