Maxim

Description

operations are done inside the MAX3420E with interrupts provided at completion so an SPI master does not need timers to meet USB timing requirements. Note: The ACKSTAT bit tells the MAX3420E that the SPI master has finished servicing a The MAX3420E has two register types, FIFOS and control registers. proven design to evaluate the MAX3420E USB peri- pheral controller with SPI interface. The EV kit-2 board is jumper-connected to an Atmel ATtiny2313. The MAX3420E SPI interface works in modes (0,0) and (1,1) without alteration. The difference is the inactive SCK level. In both modes the data is changed on Note: The version of the MAX3420E can be determined electrically (by firmware) by reading the Die Revision register. (R18); e.g., 0x01 is version 01, 0x02 is
