Transmit Data Host: This pin supplies asynchronous
serial transmit data to the host.
Receive Data Host: This pin supplies asynchronous serial
receive data from the host.
When not used, this pin must be connected to VDD.
Clear-to-Send Host: -CTSH is active only when host
hardware flow control is enabled. When -CTSH is LOW,
flow control is enabled for the host serial port, i.e., iChip
can transmit to the host. When -CTSH is HIGH, the iChip
transmitter holds its data in the serial port transmit
register. -CTSH is sampled only at the beginning of a
frame transmission. If -CTSH is raised while a character
frame is being transmitted, that frame will be completed.
Connect -CTSH to -RTSH when not in use.
Ready-to-Send Host: -RTSH is active only when host
hardware flow control is enabled. When -RTSH is LOW,
flow control is enabled for the host serial port, i.e., the
host can transmit to iChip. When -RTSH is HIGH, iChip
indicates that its receiver is busy and cannot receive data
from host. Connect -RTSH to -CTSH when not in use.
