Z32AN Series Data Sheet
10.2 Blocks
10.2.1 UART
10.2.2 Programmable Baud Rate Generator (BRG)
DS0200-003
The Smart Card function contains two blocks: a UART, and a Controller and Timing Checker:
The UART is connected to APB and supports two DMA requests, one for receive and another for transmit.
For receive, a DMA request indicates when a word is available in the receive data register. For transmit, a
DMA request indicates when a word can be accepted by the UART for transmission.
The receive channel supports a word register allowing the UART to function without DMA. The CPU can be
informed it can read a word from the UART in the by an interrupt. Words to transmit can be written through
single DMA transfers or through CPU direct accesses.
The BRG produces the Elementary Time Unit (ETU) timing reference which is the serial bit duration used for
data transfer on SC_IO. The ETU is obtained by dividing SC_CLK, with a programmable factor defined in
BRR.
