Clock, Reset, and JTAG Signals

EXTAL CLK

32 kHz external crystal clock input

XTAL CLK

32 kHz Crystal output

TDI (Test Data Input)

The test data input pin provides a serial input data stream to all TAP controllers. TDI is

sampled on the rising edge of TCK.

The test data output pin is tri-statable, providing serial output data from the Master TAP

TDO (Test Data Output) or ARM Core TAP controller. It is actively driven in the shift-IR and shift-DR controller

states of the TAP controller state machine. TDO changes on the falling edge of TCK.

TRST (Test Reset)

This active low Schmitt trigger input pin provides an asynchronously reset signal to all

TAP controllers to initialize the test controller.

The test mode select input pin is used to sequence all TAP controllers. The TAP

TMS (Test Mode Select) sequenced is determined by the tap control module and the TTS device port. TMS is

sampled on the rising edge of TCK.

TCK (Test Clock)

The test clock input pin is used to synchronize the JTAG test logic. It provides the clock

to synchronize the test logic and shift serial data to and from all TAP controllers.

RTCK (Return Test Clock)

The return test clock input pin returns the synchronization test clock to ARM

development tools to be entered from the serial debug input line.

TTS (Test TAP select)

The test tap select input pin directly controls the multiplexing logic to select between the

chip TAP and the core TAP. A logic 1 applied to the tap select input will select the chip

TAP.

MODE[1:0]

Test/boot mode select pins. In order to support a flexible development system, the

system must be capable to boot from different memories during system reset and

power-up. The four different memory maps can be selected by these two pins. All the

different boot modes start reading data at address 0x0000_0000, since this is where the

ARM7 reset vector is located.

RESETIN (Reset In)

The reset in pin is an active low Schmitt trigger input that provides reset to the internal

circuitry. The RESET input will be qualified as valid if it will be asserted for at least 3 CLK

cycles.

Bluetooth Signals

REFCTRL

(Reference Control)

The reference control pin is a dedicated output from the CRM which enables/disables

the reference clock.

REFCLK (Reference Clock)

The reference clock pin is a dedicated input into the CRM from the RF interface.

one of the four CSPI signals which program the Silicon Wave Radio.

CSPI_DOUT/CSPI_DIN: One of the three CSPI signals which program the MC13180

BT7

RF IC Radio (CSPI_DIN or CSPI_DOUT) or one of the four CSPI signals which program

the Silicon Wave Radio (CSPI_DOUT)
