DESCRIPTION NAME I/O PW, N RSA General-purpose digital I/O pin Timer_A, clock signal TACLK input P1.0/TACLK/ACLK/CA0 2 1 I/O ACLK signal output Comparator_A+, CA0 input General-purpose digital I/O pin P1.1/TA0/CA1 3 2 I/O Timer_A, capture: CCI0A input, compare: Out0 output Comparator_A+, CA1 input General-purpose digital I/O pin P1.2/TA1/CA2 4 3 I/O Timer_A, capture: CCI1A input, compare: Out1 output Comparator_A+, CA2 input General-purpose digital I/O pin P1.3/CAOUT/CA3 5 4 I/O Comparator_A+, output / CA3 input General-purpose digital I/O pin SMCLK signal output P1.4/SMCLK/C4/TCK 6 5 I/O Comparator_A+, CA4 input JTAG test clock, input terminal for device programming and test General-purpose digital I/O pin Timer_A, compare: Out0 output P1.5/TA0/CA5/TMS 7 6 I/O Comparator_A+, CA5 input JTAG test mode select, input terminal for device programming and test General-purpose digital I/O pin Timer_A, compare: Out1 output P1.6/TA1/CA6/TDI/TCLK 8 7 I/O Comparator_A+, CA6 input JTAG test data input or test clock input during programming and test General-purpose digital I/O pin P1.7/CAOUT/CA7/TDO/TDI(1) 9 8 I/O Comparator_A+, output / CA7 input JTAG test data output terminal or test data input during programming and test Input terminal of crystal oscillator XIN/P2.6/TA1 13 12 I/O General-purpose digital I/O pin Timer_A, compare: Out1 output Output terminal of crystal oscillator XOUT/P2.7 12 11 I/O General-purpose digital I/O pin(2) Reset or nonmaskable interrupt input RST/NMI/SBWTDIO 10 9 I Spy-Bi-Wire test data input/output during programming and test Selects test mode for JTAG pins on Port 1. The device protection fuse is TEST/SBWTCK 11 10 I connected to TEST. Spy-Bi-Wire test clock input during programming and test VCC 1 16 Supply voltage VSS 14 14 Ground reference NC NA 13, 15 Not connected QFN Pad NA Pad NA QFN package pad. Connection to VSS is recommended. (1) TDO or TDI is selected via JTAG instruction. (2) If XOUT/P2.7 is used as an input, excess current flows until P2SEL.7 is cleared. This is due to the oscillator output driver connection to this pad after reset. 8 Submit Documentation Feedback Copyright © 2005–2012, Texas Instruments Incorporated |
