MOSI, CS, SCK and MISO are for SPI connections. CSL and SDA are for i2c connections (ie, nunchuck, or the real time clock module). CTS and RTS are related to the UART1 along with TCD and RXD, but less often used. These are duplicated on the UEXT io bus connector.
33:40 think in binary. 3 = 0011 AND 5 = 0101 gives 0001 = 1 The bit mask selects which bits are to be considered in the output value. If the mask is 5 (0101) then only bits 2 and 0 of the value (0011) are considered ... 0*2^2=0 + 1*2^0=1.

Thanks for this valuable information!
