Under development Preliminary document
Specifications in this document are tentative and subject to change.
i = 0 to 8, 10, 11, 16 to 25, 27, 28, and 31 to 35
Note:
(3) TSCU software operation ON
The pin states are set to user settings.
Analog input control is controlled by bits CHE00 to CHE08, CHE10, CHE11, CHE16 to CHE25, CHE27,
CHE28, and CHE31 to CHE35 in registers TSIE0 to TSIE2 and bits CHSELXA0SW, CHSELXA1SW,
and CHSELXBCSW in the TSCUCR1 register.
i = 0 to 8, 10, 11, 16 to 25, 27, 28, and 31 to 35
j = 00 to 08, 10, 11, 16 to 25, 27, 28, and 31 to 35
