TENTATIVE

n PCMCIA Interface ( PCMCIA I/F )

The TX4925 has a 2 identical full PCMCIA ports.

• Provide the control signals and accepts the status signals which conform to the PCMCIA

version 2.1 standard

• Appropriate connector keying and level-shifting buffers required for 3.3V versus 5V

PCMCIA interface implementations

n Real Time Clock ( RTC )

The TX4925 has a Real Time Clock.

• 44-bit up-counter

• Interrupts on alarm, timer, and prior to RTC roll-over

• Date managed by software

n Power-down mode

The TX4925 contains support for implementation of power-down mode.

• HALT mode (stopping CPU core clock) for TX49/H2 core block

• Power-down mode (stopping input clock) for individual internal peripheral modules

• RF(Reduced Frequency) Function (1/1,1/2,1/4,1/8)

n Extended EJTAG Interface

The TX4925 contains an Extended Enhanced Joint Test Action Group ( Extended EJTAG )

interface, which provides two functions : JTAG boundary scan test that complies with

IEEE1149.1 and real-time debugging using a debug support unit ( DSU ) built into the

TX49/H2 core.

• IEEE 1149.1 JTAG Boundary Scan

• Real-time debugging functions using special emulation probe : execution control

( execution, break, step, and register / memory access ) and PC trace
