Abstract
The present invention provides a programmable generic read channel control device and circuitry for generating an output signal to control read/write operations. The programmable generic read channel control device includes a set of extension timer, a set of configuration registers, a set of AND gates, and an OR gate. The extension timers are programmed to generate a set of pulses of programmable width in response to a read gate and write gate signal. Each of the pulses is defined by a leading edge pulse and a trailing edge pulse. The set of extension timers includes a short write gate extension timer configured to generate a write gate short leading edge pulse and a write gate short trailing edge pulse defining a write gate short pulse width. The configuration registers store a set of configuration data for the pulses with each configuration register storing one configuration data for either a leading edge or a trailing edge pulse of one of the pulses. The configuration data indicates whether the associated pulse is enabled. The AND gates are arranged to receive the pulses of programmable width with each AND gate receiving either a leading edge or a trailing edge of one of the pul…
