Content
Number of channels
CSIO/UART : 4 channels (SIO0, SIO1, SIO4, SIO5)
UART only : 2 channels (SIO2, SIO3)
Clock
During CSIO mode : Internal clock or external clock as selected (Note 1)
During UART mode : Internal clock only
Transfer mode
Transmit half-duplex, receive half-duplex, transmit/receive full-duplex
BRG count source
f(BCLK), f(BCLK)/8, f(BCLK)/32, f(BCLK)/256 (when internal peripheral clock selected) (Note 2)
f(BCLK) : Internal peripheral clock operating frequency
Data format
CSIO mode :
Data length = 8 bits (fixed)
Order of transfer = LSB first (fixed)
UART mode :
Start bit = 1 bit
Character length = 7, 8, or 9 bits
Parity bit = Added or not added (when added, selectable between
odd and even parity)
Stop bit = 1 or 2 bits
Order of transfer = LSB first (fixed)
Baud rate
CSIO mode :
152 bits/sec to 2M bits/sec (at f(BCLK) = 20 MHz)
UART mode :
19 bits/sec to 156K bits/sec (at f(BCLK) = 20 MHz)
Error detection
CSIO mode :
Overrun error only
UART mode :
Overrun error, parity error, framing error (Occurrence of any of
these errors is indicated by an error sum bit)
Fixed period clock function When using SIO0, SIO1, SIO4 and SIO5 as UART, this function outputs a divided-
by-2 BRG clock from the SCLK pin.
Note 1 : The maximum input frequency of external clock during CSIO mode is 1/16 of f(BCLK).
Note 2 : When f(BCLK) is selected as the BRG count source, the BRG set value is subject to limitations.
