9 Interface UART interface Four signals are used to implement the UART function. This is only for test and debug. UART_TX and UART_RX transfer data between the two devices. The remaining two signals, UART_CTS and UART_RTS, can be used to implement RS232 hardware flow control where both are active low indicators. UART Setting User can change data format the following selection using PSKEY. However, host shall communicate with default setting UART connection initiated at first time. Baud Rate = (PSKEY_UART_BAUD_RATE) / Parameter Possible value Baud Rate 9600 ~ 4M Baud Flow Control None Parity None, Odd or Even Number of Stop Bits 1 or 2 Bits per channel 8 USB interface F1M87 has a full speed (12 Mbps) USB interface for communicating with other compatible digital devices.

10 F1M87 contains internal USB termination resistors and requires no external resistor matching. F1M87 supports the Universal serial bus specification, battery charging specification together. The below describes USB basics and architecture. - Power distribution for high and low bus-powered configurations - Power distribution for self-powered configuration, which includes USB VBUS monitoring - USB enumeration - USB suspend modes and Bluetooth low-power modes : . Global suspend . Selective suspend, includes remote wake . Wake on Bluetooth, includes permitted devices and set-up prior to selective suspend.
