Primary function: General Purpose I/O, GPIOP[21].
SDRAM Clock Input. This clock input is a delayed version of SYSCLKP. SDRAM read data is sampled into the RC32355
on the rising edge of this clock.
ATM PHY Inputs. These pins are the inputs for the ATM interface.
ATM PHY Bidirectional Signals. These pins are the bidirectional pins for the ATM interface.
TXADDR[0] Primary function: General purpose I/O, GPIOP[22].
TXADDR[1] Primary function: General purpose I/O, GPIOP[23].

Primary function: General purpose I/O, GPIOP[32].
TDM Serial Data Input. Serial data is received by the RC32355 on this signal during active input time slots.
Primary function: General purpose I/O, GPIOP[33].
TDM bus frame. TDMFP is driven if the RC32355 is a master, and is received if it is a slave.
Primary function: General purpose I/O, GPIOP[34].
TDM Clock. This input clock controls the rate at which data is sent and received on the TDM bus.
