6.3 Output Mode
The output configuration is selected setting to ‘0’
the corresponding configuration register bit
(REG_CONF 4, 13 and 15) (see paragraph 6.5).
The digital data are transferred to the related I/O
Port by means of the Output register, by using the
assembler instructions LDPE or LDPR
6.4 Alternate Functions.
Several ST52x430 pins are configurable to be
used with different functions (see table 1.1).
When an on chip peripheral is configured to use a
pin, it is mandatory to select the correct I/O mode
of the related pin.
For example: if the pin 26 (PA5/T0CLK in the SO34)
has to be used like external PWM/Timer0 clock, the
Reg_Conf 4(5) bit must be set to ‘1’.
When the signal is an input of an on-chip
peripheral, the related I/O pin has to be configured
in Input Mode.
When a pin is used as an A/D Converter input, the
related I/O pin is automatically set in tristate. The
analog multiplexer (controlled by the A/D
configuration Register) switches the analog
voltage present on the selected pin to the common
analog rail which is connected to the ADC input.
It is recommended not to change the voltage level
or loading on any port pin while conversion is
running. Furthermore it is recommended not to
have clocking pins located close to a selected
analog pin.
