4.9.18
Electrical and timing specifications of the parallel interface are presented in the subsequent sections.
4.9.19
This section describes the electrical information of the PWM. The PWM can be programmed to select one
of three clock signals as its source frequency. The selected clock signal is passed through a prescaler before
being input to the counter. The output is available at the pulse-width modulator output (PWMO) external

Interface clock. All interface signals are synchronous to the clock.
Bidirectional data bus, driven low by the link during idle. Bus ownership is determined by Dir.
Direction. Control the direction of the data bus.
Stop. The link asserts this signal for 1 clock cycle to stop the data stream currently on the bus.
Next. The PHY asserts this signal to throttle the data.
