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, I
2
C, and UART).
On the ADuC812 and the ADuC832, the I
2
C 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 I
2
C uses the standard pins. The
I
2
C 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.
