RMLD: Remote Signal Leader Value Set Register x’007EAC’
RMLD is a 16-bit access register.
fPWM1 = fSYSCLK/23,
fPWM3 = fSYSCLK/25,
fPWM5 = fSYSCLK/27,
fPWM6 = fSYSCLK/28, and
fPWM8 = fSYSCLK/210.
Do not set the leader value too
small. Leader detection and data
detection may occur
simultaneously.
SP and SPSLW: Switch clock frequencies

LD[3:0]: HEAMA data leader value
Set the four MSBs of the 6-bit leader value for HEAMA data in LD[3:0].
This 4-bit setting must be between 0 and 60 T
S
cycles. The default value is
x’6’. The two LSBs of the leader are always 0.
RMCS: Remote Signal Clock Status Register x’007EA6’
RMCS indicates the result of the short/long data detection. It is a 16-bit
access register.
LONGDF: Long data format detection
Set to 1 when long data is detected.
SHORTDF: Short data format detection
Set to 1 when short data is detected.
TSCNT[5:0]: 6-bit counter value
RMSR: Remote Signal Reception Data Shift Register x’007EA8’
RMTR: Remote Signal Reception Data Transfer Register x’007EAA’
The microcontroller shifts received data into RMSR, converting it to paral-
lel data. After it shifts in 8 bits, it loads the data byte to RMTR. The CPU
reads the data from RMTR. The data shifts from LSB to MSB. RMSR and
RMTR are 8- or 16-bit access registers.
