UIF bus
UIF is a slow (6,5 MHz) bus which may be shared with other UI functions (e.g. LCD). This ver-
sion has unidirectional TX and Rx data lines and consists of a chip enable, chip select, Tx data,
Rx data, data clock and system clock.

Clocks
The cameras and HWA can use 19.44MHz, 19.2MHz, 16.8MHz and 13MHz clocks in CCP/CCI
mode. The cameras can also use the half-frequencies. The HWA can use 16.8MHz, 13MHz,
9.72MHz, 9.6 MHz and 8.4MHz clocks for UIF mode. The clock input for any of the devices can
be DC or AC coupled. The camera and HWA is supplied from the same clock input.

Vibra
A vibra alerting device is used to generate a vibration signal for an incoming call. The vibra is
located in the bottom end of the phone and connection is done with SMD. The vibra is control-
led by a PWM signal from the UEMEK. The Frequency can be set to 64, 129, 258 or 520 Hz
and duty cycle can vary between 3% and 97%.
