13.4 Universal Asynchronous Receiver-Transceiver Serial Interface

13.4.1 Features

Serial interface 3 is a UART serial interface. Its features are described below.
• Parity
• Character length 7 bits, 8 bits
• Transmission and reception bit sequence
• Clock source
• Dedicated counter built in
• Maximum bit rate
• Error detection during reception
• Buffers
• Interrupts
• Transmission interrupt function
13-36
None, 0 fixed, 1 fixed, even, odd
LSB or MSB selectable
IOCLK
Timer 2 or timer 8 underflow
External clock
Has an internal 7-bit counter that permits fast bit rates even with a clock source that
operates at a comparatively low frequency.
230.4 kbit/s (when IOCLK = 15 MHz)
Parity errors, overrun errors, flaming error
Independent buffers for transmission and reception:
Reception and transmission buffers are both double buffers
Transmission interrupts:
"Transmission end" or "transmission buffer empty" selectable
Reception interrupts:
"Reception end" or "reception end with error" selectable
Transmissions can be interrupted and resumed with the proper external pin and register
settings.
