Universal Zilog Interface
PS006614-1208
The eZ80190 device features two on-chip Universal Zilog Interface (UZI) devices. Each
UZI contains three serial communication controller blocks: a Serial Peripheral Interface
(SPI), a Universal Asynchronous Receiver/Transmitter (UART), and an Inter-Integrated
Circuit serial bus (I
trollers can be enabled. The UZI devices are connected to GPIO pins on Port C (UZI 1)
and Port D (UZI 0). Ports C and D must be configured for alternate-function I/O to allow
the UZI devices to communicate via the Port C and D pins. Each UZI also contains control
registers and a Baud Rate Generator (BRG) that generates a lower-frequency clock for the
SPI and UART devices. The I
block, including the Baud Rate Generator, is inactive when none of the serial devices are
selected.
