Cypress CY4672 Serial Command Protocol, Serial Response Protocol, Command Command Description

Manufacturing Test Support, MTK

Table 6-1. Serial Command Protocol

Command		Command Description
ST		START STANDARD TEST
Parameters	CL <power level>	CONFIGURE POWER LEVEL (0-7)
	PN <PN code>	CONFIGURE PN CODE INDEX (0-7)
	TT <tx error threshold>	CONFIGURE TX ERROR THRESHOLD (0-65535) units of bit errors
	RT <rx error threshold>	CONFIGURE RX ERROR THRESHOLD (0-65535) units of bit errors
Test	C1 <channel>	CONFIGURE CHANNEL (0-77)
	C2 <channel>	CONFIGURE SECOND CHANNEL (0-77)
Standard
	CB <# of bytes>	CONFIGURE NUMBER OF BYTES/PACKET PAYLOAD (0-15)
	C3 <channel>	CONFIGURE THIRD CHANNEL (0-77)
	CP <# of packets>	CONFIGURE NUMBER OF PACKETS (0-255)
TC <time>		TRANSMIT CARRIER (0-255)
TR <time>		TRANSMIT RANDOM (0-255)
SC <channel> <PN code>		SET COMMUNICATION (0-77) (0-7) (0-7) (0-16)
		Note The device transmits on <channel> + 2.
<power level> <correlator threshold>
		For example, 2=2.402 GHz
PD <packet data>		SET PACKET DATA (ASCII representation of hexadecimal numbers
		without any prefix, i.e. 5A 34 CB)
CA <crystal adjust>		SET CRYSTAL FREQUENCY ADJUST VALUE (0-63)
RE		RESTORE NVRAM DEFAULTS
CS		SHOW CURRENT CONFIGURATION
HE		SHOW HELP MENU

Every serial command issued by the PC is returned with a response once the command is complete. The valid responses are shown in Table 6-2.

Table 6-2. Serial Response Protocol

REPORT	REPORT DESCRIPTION
OK	COMMAND COMPLETE
CE	COMMAND ERROR
TE <transmit error count>	TX ERROR COUNT (units of bit errors)
RE <receive error count>	RX ERROR COUNT (units of bit errors)

All serial commands must end in either a carriage return or carriage return and line feed. All responses end with a carriage return and linefeed.

The serial port settings for the MTK Tester are shown in Table 6-3 on page 103. Neither software nor hardware handshake is supported.
