16.3.6
CIRRDR0 to CIRRDR17 are an 18-byte register that stores receive data, totaling to 18 bytes.
CIRRDR0 to CIRRDR17 share one byte of the register address. A receive data in CIRRDR should
be read after the CIR has finished data reception (CIRBUSY = 0). If CIRRDR is read during the
CIR reception (CIRBUSY = 1), an undefined value is read.
16.3.7
HHMIN and HHMAX control the noise canceler circuit, and specify the minimum and maximum
high-level period for a header or repeat header, and low-level period for a stop.

Description
Stores the CIR receive data.
Description
Receive Byte Counter
The RFMBN value is incremented by 1 (+1) each
time a byte is received. However, when RFMBN
reaches B'10011, an overrun error occurs. At this
time, a receive data is not stored in CIRRDR.
When CIRRDR is read after the CIR has finished
receiving (CIRBUSY = 0), RFMBN is decremented
by 1 (−1). When CIRRDR is read while RFMBN =
B'00000, an undefined value is read. When CIRRDR
is read during the CIR reception, an undefined value
is read and RFMBN is not decremented.
Reserved
The initial value should not be changed.
Specifies the minimum high-level period for a header
or repeat header and the minimum low-level period
for a stop.
