Terminal Configuration and Functions

Table 4-1. Unused Balls Specific Connection Requirements (continued)

BALLS

CONNECTION REQUIREMENTS

V28 / F18 / E20 / E23 / D21 / C20 / C21 / AG25 / AE28 / AD28 / Y27

/ G27 / H28 / K28 / M27 / F17 / C25

These balls must be connected to the corresponding power supply

through an external pull resistor if unused

AF14 (rtc_iso)

This ball should be connected to the corresponding power supply

through an external pull resistor if unused; or can be connected to

F22 (porz) when RTC unused (level translation may be needed)

AB17 (rtc_porz)

This ball should be connected to VSS when RTC is unused; or can

be connected to F22 (porz) when RTC unused (level translation may

be needed)

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.

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 take into account 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. Hxx/LFx: This column shows if the functionality is applicable for TDA2Hxx / TDA2LFx devices. Note

that the ball characteristics table presents the functionality of TDA2Sxx device.

Hxx - TDA2HGx; TDA2HVx; TDA2HFx;

LFx - TDA2LFx

5. MUXMODE: Multiplexing mode number:

a. MUXMODE 0 is the primary mode; 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
