FLVⅣ
When data exists in FLVⅢ, FLVⅣ indicates the number of data bytes of the following frames that do the reception
completion in AUTO_FLV_CP mode.
●TRCRⅡ: Transmit / Receive Control Register
TRCRⅡ is a register that sets each environment of the transmission and the reception.
TRCRⅡ1 : TXE_C_CLR (TXE_EI Counter Clear)
When this bit is set to “1”, TXE_EI Counter is cleared.
After it clears, this bit is set to “0” automatically.
TRCRⅡ2 : WRE_C_CLR (WRE_EI Counter Clear)
When this bit is set to “1”, WRE_EI Counter is cleared.
After it clears, this bit is set to “0” automatically.
●TXE_C: TXE_EI Counter
TXE_C is a register that counts the generation frequency of TXE_EI.
TXE_C8 TXE_C7 TXE_C6 TXE_C5 TXE_C4 TXE_C3 TXE_C2 TXE_C1 TXE_C0
TXE_C is effective in many windows transmit mode.
The initial value is 0.
TXE_C is initialized by TXE_C_CLR=1 or transmit / receive mode change.
