Bank 1, Offset 03h
This register is set to 00h on power-up of V
Bank 1, Offset 04h
Bank 1, Offset 05h
This register defines the station address to be compared with the address contained in the incoming CEIR message. If CEIR is enabled
(bit 0 of the IRWCR register is 1) and an address match occurs, then bit 5 of the WKSR register is set to 1.
This register is set to 00h on power-up of V
Bank 1, Offset 06h
Each bit in this register determines whether the corresponding bit in the IRWAD register takes part in the address comparison. Bits 5, 6,
and 7 must be set to 1 if the RC-5 protocol is selected.
This register is set to E0h on power-up of V
Bank 1, Offset 07h
This register holds the received address to be compared with the address contained in the IRWAD register.
This register is set to 00h on power-up of V
These two registers (IRWTR0L and IRWTR0H) define the low and high limits of time range 0 (see Table 5-26 on page 123). The values
are represented in units of 0.1 ms.
• RC-5 protocol: The bit cell width must fall within this range for the cell to be considered valid. The nominal cell width is 1.778 msec for
• NEC protocol: The time distance between two consecutive CEIR pulses that encodes a bit value of 0 must fall within this range. The

a 36 KHz carrier. IRWTR0L and IRWTR0H should be set to 10h and 14h, respectively. (Default)
nominal distance for a 0 is 1.125 msec for a 38 KHz carrier. IRWTR0L and IRWTR0H should be set to 09h and 0Dh, respectively.
