LC8740C8A/B2A/96A
ÂHigh-speed Clock Counter
1) Can count clocks with a maximum clock rate of 28.2MHz (at a main clock of 14.1MHz).
2) Can generate output real-time.
ÂSIO
⢠SIO0: 8-bit synchronous serial interface
1) LSB first/MSB first mode selectable
2) Built-in 8-bit baudrate generator (maximum transfer clock cycle =4/3 tCYC)
3) Automatic continuous data transmission (1 to 256 bits, specifiable in 1 bit units, suspension and resumption of
data transmission possible in 1 byte units)
⢠SIO1: 8-bit asynchronous/synchronous serial interface (bus mode 1 system)
Mode 0: Synchronous 8-bit serial I/O (2- or 3-wire configuration, 2 to 512 tCYC transfer clocks)
Mode 1: Asynchronous serial I/O (half-duplex, 8 data bits, 1 stop bit, 8 to 2048 tCYC baudrates)
Mode 2: Bus mode 1 (start bit, 8 data bits, 2 to 512 tCYC transfer clocks)
Mode 3: Bus mode 2 (start detect, 8 data bits, stop detect)
⢠SIO6: 8-bit asynchronous/synchronous serial interface (bus mode 2 system)
Mode 0: Synchronous 8-bit serial I/O (2- or 3-wire configuration, 2 to 512 tCYC transfer clocks)
Mode 1: Asynchronous serial I/O (half-duplex, 8 data bits, 1 stop bit, 8 to 2048 tCYC baudrates)
Mode 2: Bus mode 1 (start bit, 8 data bits, 2 to 512 tCYC transfer clocks)
Mode 3: Bus mode 2 (start detect, 8 data bits, stop detect)
