DA1458x Production Line Tool reference CLI

Example:

prodtest –p 14 xtrim rd

Output example:

status = 0

trim_value = 500

7.14 xtrim wr

Description: writes a value into the XTAL16M trimming register. The new value is written

immediately and it is already effective when the prodtest program finishes executing this command.

Syntax: prodtest -p <COM port number> xtrim wr <trim_value>

Parameters:

●

trim_value is the unsigned 16-bit decimal value to be written into the XTAL16M trimming register.

Example:

prodtest –p 14 xtrim wr 500

Output example:

status = 0

7.15 xtrim en

Description: enables XTAL16M output on GPIO P0_5. The command takes effect immediately.

Syntax: prodtest -p <COM port number> xtrim en

Example:

prodtest –p 14 xtrim en

Output example:

status = 0

Note 1

This command can also be used to enable the 32kHz clock on a GPIO 0_6. To do this two additional

registers need to be set using the write_reg16 command (see section 7.31)

Enable 32kHz clock in CLK_32K_REG, set bit 0 and bit 7 to '1'

Set GPIO P0_6 to output mode. In P06_MODE_REG, set bit 8 and 9 to '1'

Example:

prodtest –p 14 write_reg16 50000020 079D

prodtest –p 14 write_reg16 50003012 0300

Output example:

status = 0

7.16 xtrim dis

Description: disables XTAL16M output on GPIO P0_5. The command takes effect immediately.

Note 2

This command also disables:

XTAL32K output on GPIO P0_6

RC16M output on P0_7

RC32K output on P1_0

Syntax: prodtest -p <COM port number> xtrim dis

Example:

prodtest –p 14 xtrim dis
