LPC1758 PCONP Register PCSPI, PCSSP1 and PCSSP0

[lpcware]

Table 46 in the manual shows 3 locations for SPI interface to turn ON namely PCSPI, PCSSP1 and PCSSP0
Question
To power up the SPI interface do all 3 bit locations(PCSPI, PCSSP1 and PCSSP0) have to be set to 1 or just PCSPI? I am trying to communicate SSP1 and SSP0 and the reason for the question is because I would like to know if PCSPI will turn on both by Default.
I haven't written the code but that would be the true way to find out what each pin does.

The SPI is configured using the following registers:
1. Power: In the PCONP register (Table 46), set bit PCSPI.

Chapter 18: LPC176x/5x SSP0/1

The two SSP interfaces, SSP0 and SSP1 are configured using the following registers:
1. Power: In the PCONP register (Table 46), set bit PCSSP0 to enable SSP0 and bit
PCSSP1 to enable SSP1.
