Content
Number of channels
CSIO/UART: 4 channels (SIO0,SIO1,SIO4,SIO5)
UART-only : 4 channels (SIO2,SIO3,SIO6,SIO7)
Clock
During CSIO mode : Internal clock or external clock selectable (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 is
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 = With or without (odd/even selectable)
Stop bit = 1 or 2 bits
Order of transfer: LSB first (fixed)
Baud rate
CSIO mode
: 152 bits/second to 2 Mbits/second (when f(BCLK) = 20 MHz)
UART mode : 19 bits/second to 156 Kbits/second (when f(BCLK) = 20 MHz)
Error detection
CSIO mode
: Overrun error only
UART mode : Overrun, parity, and framing errors
(Any error if occurs is indicated by an errorsum bit)
Fixed period clock
When using SIO0, SIO1, SIO4, or SIO5 in UART mode, this function outputs a
output function divided-by-2 clock of BRG from the SCLK pin.
Note 1: During CSIO mode, the maximum input frequency of an external clock is f(BCLK) divided by 16.
Note 2: If f(BCLK) is selected for the BRG count source, the BRG set value is subject to limitations.
