example when the supply voltage to the module experiences a Brown- Out (momentary dip in the supply vo ltage level), or a rapid power cycle i.e. the power is switched off and th en on within 1second, there is a possibility that the module can ent er an unknown state of operation. It is strongly recommended that the application hardware onto which t ...

2.4 SPI Bus The module is a slave device that uses terminals SPI_MOSI, SPI_MISO, SPI_CLK and SPI_CSB. This interf ace is used for program firmware update. Note: The designer should be aware that no security protection is built into the hardware or firmwa re associated with this port, so the terminals should not be permanently connected in a PC appl ...

Notes: • UART_RX, UART_TX, UART _CTS, UART_RTS, UART_RI, UART_DCD and UART_DSR are all 3.3v level logic. For example, when RX and TX are idle they will be sitting at 3.3V. Conversely for handshaking pins CTS, RTS, R I, DCD, DSR a 0v is treated as an assertion. • Pin 6 (UART_RI) is active low. It is normally 3.3v. When a remote device initiates ...
