SelectMap accepts FPGA image but does not enter the startup sequence

Question

I am loading the image of my Spartan 6 and it seems that it cannot go to the final step of the process: the "Startup Sequence". After I load the image byte by byte, and add a lot of extra clock cycles at the end, the status register of the FPGA reveals that there have been no errors, and GHIGH STATUS status being high means that:

The device has properly received its entire configuration data stream. The device is ready to enter the Startup sequence.

I have checked that the INITB and PROGRAMB are not pulled low preventing the startup sequence, and in the status register everything looks very promising.

Why is my Spartan 6 not entering the startup sequence after it received and is happy with the image?

(Below is the status register after configuration.)

[0] CRC ERROR : 0
[1] IDCODE ERROR : 0
[2] DCM LOCK STATUS : 0
[3] GTS_CFG_B STATUS : 0
[4] GWE STATUS : 0
[5] GHIGH STATUS : 1
[6] DECRYPTION ERROR : 0
[7] DECRYPTOR ENABLE : 0
[8] HSWAPEN PIN : 1
[9] MODE PIN M[0] : 0
[10] MODE PIN M[1] : 1
[11] RESERVED : 0
[12] INIT_B PIN : 1
[13] DONE PIN : 0
[14] SUSPEND STATUS : 0
[15] FALLBACK STATUS : 0

Solved it! The problem turned out to be that I was using the JTAG clock for the startup sequence, rather than CCLK. The choice of clock is specified inside the "Startup Options" inside ISE.
