MM232R USB - Serial UART Development Module Incorporating Clock Generator
Section 9
Description
Enable transmit data for RS485
Goes low after the device is configured by USB, then high
during USB suspend. Can be used to control power to
external logic in high power designs. Needs 10k pull up to
VCC.
Transmit data LED drive – pulses low when transmitting
data via USB.
Receive data LED drive – pulses low when receiving data
via USB.
LED drive – pulses low when transmitting or receiving
data via USB. See
Goes low during USB suspend mode. Typically used to
power down an external TTL to RS232 level converter I.C.
in USB to RS232 converter designs.
48MHz Clock output.
24 MHz Clock output.
12 MHz Clock output.
6 MHz Clock output.
CBUS bit bang mode option. Allows up to 4 of the CBUS
pins to be used as general purpose I/O. Configured
individually for CBUS0, CBUS1, CBUS2 and CBUS3 in the
internal EEPROM. A separate application note describes in
more detail how to use CBUS bit bang mode.
