Data Sheet

GPIO1[TS1E]

GPIO2[TS2E]

General Purpose I/O

Even Trace execution status. To access this function, software must

toggle a DCR bit.

I/O[O]

3.3V LVTTL

1, 6

GPIO3[TS1O]

General Purpose I/O

Odd Trace execution status. To access this function, software must

toggle a DCR bit.

GPIO5:8[TS3:6]

General Purpose I/O

Trace status. To access this function, software must toggle a DCR

bit.

I/O[O]

5V tolerant

3.3V LVTTL

1, 6

GPIO9[TrcClk]

General Purpose I/O

Trace interface clock. A toggling signal that is always half of the CPU

core frequency. To access this function, software must toggle a DCR

bit.

Note: Initialization strapping must hold this pin low (0) during reset.

I/O[O]

5V tolerant

3.3V LVTTL

GPIO24

General Purpose I/O.

Note: The pull-up initialization strapping resistor must be 1k

Ω rather

than 3k

Ω in order to overcome the internal pull-down resistor.

I/O

TestEn

Test Enable. Used only for manufacturing tests. Pull down for normal

operation.

1.8V CMOS

w/pull-down

TmrClk

An external clock input that can be used to clock the timers in the

CPU core.

Signal Functional Description (Sheet 7 of 8)

Multiplexed signals are shown in brackets following the first signal name assigned to each multiplexed ball.

Notes:

1. Receiver input has hysteresis.

2. Must pull up. See “Pull-Up and Pull-Down Resistors” on page 29 for recommended termination values.

3. Must pull down. See “Pull-Up and Pull-Down Resistors” on page 29 for recommended termination values.

4. If not used, must pull up.

5. If not used, must pull down.

6. Strapping input during reset; pull up or pull down as required.

7. Pull-up may be required. See “External Bus Control Signals” on page 29.
