PIN configuration for ISP mode

Hi,

In LPC55S1x/LPC551x datesheet, it says:

Function # 0
PIO1_2 — General-purpose digital input/output pin.
Remark: In ISP mode, this pin is set to the High Speed
SPI SCK function (Flexcomm 8).

Does it mean Function # need to be set to 0 to make this pin work as High Speed
SPI SCK function in ISP mode? If yes, how to set Function # for ISP mode? Can I set different Function # for ISP mode and non-ISP mode?

Regards,

Winston

LPC55xx
