Clarifications/Corrections to the Data
Sheet:
In the device data sheets, DS21655A and DS21690A,
the following clarifications and corrections should be
noted:
DS80261A-page 2
The MCP215X issues two RR packets upon entry
into Normal Response Mode (NRM) prior to the
Primary Device sending a packet.
This does not appear to be a compatibility issue
with current IrDA compatible devices.
Work around
None
None.
Enhancements for Rev B Devices:
The following device enhancements should be noted
for Silicon Rev. B devices (from Silicon Rev. A devices):
1.
2.
3.
The MCP2150 now has retransmit capability for
outgoing IR Packets. This retransmission
occurs when the number of “packets” sent does
not match the number “packets” received. The
MCP215X will attempt to retransmit a “packet”
only a limited number of times.
The Host UART Receive Buffer window (# of
bytes that MCP2150 Host UART can receive
before de-asserting CTS) was increased from
40 to 60 bytes. This provides consistency with
the MCP2155.
Increased the number of initial BOF characters
from 1 BOF to 11 BOF for better compatibility
with future IrDA Standard devices.
