10 / 415 page  AM5728, AM5726 SPRS915O – MARCH 2014 – REVISED OCTOBER 2015 www.ti.com Table 4-1. Unused Balls Specific Connection Requirements (continued) Balls Connection Requirements These balls must be connect to the corresponding power supply AF14 / V28 / F18 / E20 / E23 / D21 / C20 / C21 through an external pull resistor if unused AB17 This ball must be connected to F22 (porz) if unused NOTE All other unused signal balls with a Pad Configuration Register can be left unconnected with their internal pullup or pulldown resistor enabled. NOTE All other unused signal balls without Pad Configuration Register can be left unconnected. 4.2 Ball Characteristics Table 4-2 describes the terminal characteristics and the signals multiplexed on each ball. The following list describes the table column headers: 1. BALL NUMBER: Ball number(s) on the bottom side associated with each signal on the bottom. 2. BALL NAME: Mechanical name from package device (name is taken from muxmode 0). 3. SIGNAL NAME: Names of signals multiplexed on each ball (also notice that the name of the ball is the signal name in muxmode 0). NOTE Table 4-2 does not consider the subsystem multiplexing signals. Subsystem multiplexing signals are described in Section 4.4, Signal Descriptions. NOTE In the Driver off mode, the buffer is configured in high-impedance. 4. 28/26: This column shows if the functionality is applicable for AM5728 / AM5726 devices. Note that the ball characteristics table presents a functionality of super set. If the cell is empty it means that the signal is available in all devices. 28 - AM5728 26 - AM5726 5. MUXMODE: Multiplexing mode number: (a) MUXMODE 0 is the primary muxmode; this means that when MUXMODE=0, the function mapped on the pin corresponds to the name of the pin. The primary muxmode is not necessarily the default muxmode. NOTE The default muxmode is the mode at the release of the reset; also see the RESET REL. MUXMODE column. (b) MUXMODE 1 through 15 are possible muxmodes for alternate functions. On each pin, some muxmodes are effectively used for alternate functions, while some muxmodes are not used. Only MUXMODE values which correspond to defined functions should be used. 6. TYPE: Signal type and direction: – I = Input – O = Output 10 Terminal Configuration and Functions Copyright © 2014–2015, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links: AM5728 AM5726 |
