Serial Interface

13-3

13.2.1

Features

Serial interface 0

 is a general-purpose serial interface for which clock sync mode, UART mode, or I2C mode can

be specified.  The features of each mode are described below.

<Clock synchronous 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

1/2, 1/8, or 1/32 of IOCLK

1/8 of timer 3 or timer 9 underflow, 1/2 of timer 9 underflow

External clock

• Maximum bit rate

7.5 Mbit/s (when IOCLK is 15 MHz)

• Error detection during reception

Parity errors, overrun 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
