IFCLK
I/O/Z
Z
Interface Clock, used for synchronously clocking data into or out of the
slave FIFO’s. IFCLK also serves as a timing reference for all slave FIFO
control signals and GPIF. When internal clocking is used (IFCONFIG.7 = 1)
the IFCLK pin can be configured to output 30/48 MHz by bits IFCONFIG.5
and IFCONFIG.6. IFCLK may be inverted, whether internally or externally
sourced, by setting the bit IFCONFIG.4 =1.

USB Wakeup
. If the 8051 is in suspend, asserting this pin starts up the
oscillator and interrupts the 8051 to allow it to exit the suspend mode.
Holding WAKEUP asserted inhibits the MoBL-USB
chip from
suspending. This pin has programmable polarity (WAKEUP.4).
