Note:
For UC3 and ATSAM libraries, an n- channel library supports up to n channels using n
consecutive pins on different SNS and SNSK ports (or) supports up to n channels using (2*n)
consecutive pins on the same port used for both SNS and SNSK lines. This library requires 1 or 2
UC3 or ATSAM ports. In addition to this, for the ATSAM libraries the pins can be configured on 3
ports based on the configuration selected.
NOTE:
pins.In those devices, the mapping is given as below:
Example SNS=A and SNSK=X, So channel 0 will be (SNS0 = GPIO0_Pin0 and SNSK0 =
GPIO3_Pin0 ).
Similarly,Example SNS=X and SNSK=X, So channel 0 will be (SNS0 = GPIO3_Pin0 and SNSK0
= GPIO3_Pin1 ).
•
When a library supports 4 channels using 8 consecutive pins on the same port, the SNS and
SNSK pins are allocated alternately. This is valid for all the libraries mentioned above.
Usage of intraport configuration requires more code memory than the interport configuration.
The values mentioned in the Library_selection_Guide.xls are for interport configurations. The
memory consumption for intra-port will be higher to the values mentioned in the
Library_selection_Guide.xls
The configurations on pin configurability should be used in conjunction with the rules for
assigning the pins that are described in section 5.8.2
16-channel library – supports up to 16 channels out of which, 8 channels with 8 pins for
SNS1 and SNSK1 are available on different ports and the other 8 channels with 8 pins
are available on a different pair of SNS2 and SNSK2 ports. This library requires a total of
4 ports.
Some of the devices in UC3 family has ports having more than 32 pins or less than 32
GPIO Port0 -> A
GPIO Port1 -> B
GPIO Port2 -> C
GPIO Port3 -> X
