LAUNCHXL-F280049C: CLB out for GPIO

Hi,

I'm trying to send CLB out to GPIO pin.

I can make gpio output using CLBx_4 and CLB_5 out;

But I can't it using CLBx_6 and CLBx_7

I wonder is it possible to gpio output for CLBx_6 and 7?

If it is possible, is there mistake in my configuration?

1. GPIO14 is used OUTPUTXBAR3

2. in sysconfig OUTLUT6 is connected.

-----------------------------------------------------------------------------------------------------------------------

GPIO_setPinConfig(GPIO_14_OUTPUTXBAR3);
GPIO_setDirectionMode(14, GPIO_DIR_MODE_OUT);
GPIO_setPadConfig(14, GPIO_PIN_TYPE_STD);

XBAR_setOutputMuxConfig(XBAR_OUTPUT3, XBAR_OUT_MUX00_ECAP1_OUT);
XBAR_enableOutputMux(XBAR_OUTPUT3, XBAR_MUX00);

CLB_setOutputMask(CLB1_BASE, 1 << 6, true);
