Serial Interface
13-4
<UART mode>
•Parity None, 0 fixed, 1 fixed, even, odd
•Character length 7 bits, 8 bits
•Transmission and reception bit sequence
LSB or MSB selectable
•Clock source 1/8 or 1/32 of IOCLK
1/8 of timer 3 or timer 9 underflow
1/8 of external clock
•Maximum bit rate
19.2 kbit/s (when IOCLK is 15 MHz)
•Error detection during reception
Parity errors, overrun errors, framing errors
•Buffers Independent buffers for transmission and reception
Reception and transmission buffers are both double buffers
•Interrupts Transmission interrupts:
"Transmission end" or "transmission buffer empty" selectable
Reception interrupts:
"Reception end" or "reception end with error" selectable
<I2C mode>
•Master transmission, master reception possible (No start sequence conflict detection function)
