Preliminary Specification
This is a preliminary specification and is subject to change.
22. Remote Control Signal Receiver
22.3.2.1 Header Detection (PMC0, PMC1)
When the HDEN bit in the PMCiCON0 register is 1 (header enabled), the following occur by detecting
data 0, data 1, or special data prior to header.
• The REFLG bit in the PMCiSTS register becomes 1 (error occurs).
• Bits PTD0FLG, PTD1FLG, and SDFLG in the PMCiSTS register remain unchanged.
• Registers PMCDAT0 to PMCDAT5 remain unchanged.
When detecting header in PMC0, set the SDEN bit in the PMC0CON0 register to 0 (special data
disabled).
22.3.2.2 Special Data Detection (PMC0)
When the SDEN bit in the PMC0COM0 register is 1 (special data enabled), special data can be
detected. When detecting the special data, set the HDEN bit in the PMC0CON0 register to 0 (header
disabled).
22.3.2.3 Receive Data Buffer (PMC0)
There is a 6-byte (48-bit) buffer for storing received data. When the data exceeds 48 bits, the buffer is
sequentially overwritten from the first bit. Refer to 22.2.12 “PMC0 Receive Data Store Register i
(PMC0DATi) (i = 0 to 5)” and 22.2.11 “PMC0 Receive Bit Count Register (PMC0RBIT)”.
