13.3 Clock Synchronous Serial Interface

13.3.1

Features

Serial interfaces 1 and 2

are clock synchronous serial interfaces. Their features are described below.

• 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 (for either serial interface 1 or 2)

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

(for either serial interface 1)

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

(for either serial interface 2)

External clock (for either serial interface 1 or 2)

• 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
