47 / 437 page ![]() 2.0 Signal/Pin Description and Configuration (Continued) Revision 1.07 47 www.national.com IOPE7-0 21-20, 34, 4, 68-65 25-24, 44, 2, 90-87 IINTS VCC General-Purpose Input Port. These pins serve as input-only pins. The GPIO registers are accessible by the core for read and configuration. The pins may be used as GPIO or assigned to their respective alternate functions. IOPE0-3 and IOPE5 do not have an internal pull-up resistor option. Note that IOPE0-3 and IOPE6-7 are not 5V tolerant. See Section 2.4 on page 54 for GPIO pin assignment to alternate functions. See Section 4.5 on page 113 for further details on the GPIO pins and their functionality. Signal 128-Pin LQFP 176-Pin LQFP I/O Buffer Type Power Well Description |
