GENERAL DESCRIPTION (continued)
The parts also incorporate additional analog functionality with
two 12-bit DACs, power supply monitor, and a band gap
reference. On-chip digital peripherals include two 16-bit ∑-.
DACs, a dual output 16-bit PWM, a watchdog timer, a time
interval counter, three timers/counters, and three serial I/O
ports (SPI, I2C, and UART).
On the ADuC812 and the ADuC832, the I2C and SPI interfaces
share some of the same pins. For backwards compatibility, this
is also the case for the ADuC841/ADuC842/ADuC843.
However, there is also the option to allow SPI operate separately
on P3.3, P3.4, and P3.5, while I2C uses the standard pins. The
I2C interface has also been enhanced to offer repeated start,
general call, and quad addressing.
On-chip factory firmware supports in-circuit serial download
and debug modes (via UART) as well as single-pin emulation
mode via the EA pin. A functional block diagram of the parts is
shown on the first page.
