5.2.7 Serial Host Connection
iChip supports a full-duplex serial communications link with the host processor. Full EIA -232-
D hardware flow control, including Tx, Rx, CTS, RTS, DTR and DSR lines, is supported.
iChip supports standard baud rate configurations from 2,400 bps up to 3Mbps on the host
asynchronous serial communications channel. A fixed baud rate may be defined by using the
AT+iBDRF command. Without a fixed baud rate setting, iChip defaults to auto baud rate
detection.
5.2.8 Parallel Host Connection
The high-speed parallel interface (HPI) is a glueless connection to an 8-bit parallel port.
