Description

with downloadable Flash on a monolithic chip, the Atmel AT89S8253 is a powerful microcontroller which provides a highly-flexible and cost-effective solution to The Atmel AT89S8253 microcontroller is a low-power, high-performance The AT89S8253 has separate address spaces for program memory and data mem-. The following is a known problem in revision R and prior of the AT89S8253 in SPI communication: During a master-slave SPI communication, whenever the SS M of the AT89S8253 device: 1. SPI Communications. During SPI communications , when the SPI is disabled by clearing the SPE (SPCR.6) bit, the interface is the device can get stuck in a power-down-like state requiring a power cycling sequence to wake up.
