Global RAM Window Control Register (GRWCR)
This bit is used to select a window for the switching of registers that are allocated to addresses from 000A 83A0h to
000A 8681h.
[Registers allocated when the RPAGE bit is set to 0 (window 0 selected)]
Receive rule entry registers: GAFLIDLj, GAFLIDHj, GAFLMLj, GAFLMHj, GAFLPLj, GAFLPHj (j = 0 to 15)
RAM test registers: RPGACCr (r = 0 to 127)
[Registers allocated when the RPAGE bit is set to 1 (window 1 selected)]
Receive buffer registers: RMIDLn, RMIDHn, RMTSn, RMPTRn, RMDF0n to RMDF3n (n = 0 to 15)
Receive FIFO access registers: RFIDLm, RFIDHm, RFTSm, RFPTRm, RFDF0m to RFDF3m (m = 0, 1)
Transmit/receive FIFO access registers: CFIDL0, CFIDH0, CFTS0, CFPTR0, CFDF00 to CFDF30
Transmit buffer registers: TMIDLp, TMIDHp, TMPTRp, TMDF0p to TMDF3p (p = 0 to 3)
Transmit history buffer access register: THLACC0
Address(es): RSCAN.GRWCR 000A 838Ah
