4.1.3 LCD alternate functions (combiports)
PC0 to PC7 can also be individually defined as 8
LCD segment output by setting DDRC, ORC and
DRC registers as shown in
Table 12
.
On the contrary with other I/O lines, the reset state
is the LCD output mode. These 8 segment lines are
recognised as S33..S40 by the embedded LCD
controller drive.
4.1.4 SPI alternate functions
PB6/Sin and PB5/Scl pins must be configured as
input through the DDR and OR registers to be
used data in and data clock (Slave mode) for the
SPI. All input modes are available and I/O's can be
read independantly of the SPI at any time.
PB7/Sout must be configured in open drain output
mode to be used as data out for the SPI. In output
mode, the value present on the pin is the port data
register content only if PB7 is defined as push pull
output, while serial transmission is possible only in
open drain mode.
