TPS Registers
5-19
S2_S_IE
Stage 2 Synchro Interrupt Mask
D2 R/W
The microprocessor sets this bit to enable an interrupt
when deinterleaver/Reed-Solomon decoder
synchronization is acquired.
The initial value of S2_S_IE is 0.
Start_LS_IE
Start Pulse Synchro Lost Interrupt Mask
D1 R/W
The microprocessor sets this bit to enable an interrupt
when FFT start pulse loses lock.
The initial value of Start_LS_IE is 0.
Start_S_IE
Start Pulse Synchro Interrupt Mask
D0 R/W
The microprocessor sets this bit to enable an interrupt
when FFT start pulse achieves lock.
The initial value of Start_S_IE is 0.
5.4 TPS Registers
The TPS registers have two different functions, depending on whether
they are read or written to. When read, they indicate the contents of the
last correctly received TPS structure. When written to, they set the next
operation mode of the DTTV demodulator. The mode change does not
take effect until the “change mode” command is issued by setting the
“change mode” bit in the mode register. The meaning of the bits
contained in the TPS registers are described in the ETSI Specication.
