frame size, 2) simplify multi-frame windowing for
transmit data blocks that are larger than the
maximum packet size and, 3) constrain the SCE
transmitter during loopback testing. NOTE: only
the Tx Data Size register is used for IrDA FIR
loopback testing; only the Rx Data Size register
is required for Consumer IR loopback tests. If
the Tx Data Size register is zero, the IrDA
transmit message size is unlimited; i.e., the
transmitter will operate until the FIFO is empty.
The Tx Data Size High register is the Tx Data
Size high nibble.
Tx Data Size Low (Address 4)
The Tx Data Size Low register is the Tx Data
Size low byte.
Rx Data Size High (Address 5)
Rx Data Size High, bits 0 - 3
The Rx Data Size register specifies the IrLAP-
39
bytes per IrDA receive message frame.
register is used to check each IrDA FIR receive
frame for valid data size and to constrain the
SCE receiver during Consumer IR loopback
testing. NOTE: only the Rx Data Size register is
required for Consumer IR loopback tests; only
the Tx Data Size register is required for IrDA FIR
loopback tests.
tests, program the Rx Data Size register with
Test_byte_count_1. If the Rx Data Size register
is zero the IrDA receive message size is
unlimited; i.e., a size error cannot occur because
frame size checking is disabled. The Rx Data
Size High register is the Rx Data Size high
nibble.
Rx Data Size Low (Address 6)
The Rx Data Size Low register is the RxData
Size low byte.
For Consumer IR loopback
