Table 8-3 Control Registers of GMS81C2020
These registers of shaded area can not be access by bit manipulation instruction as " SET1, CLR1 ", but should be access by reg-
ister operation instruction as " LDM dp,#imm ".
1.The register BITR and CKCTLR are located at same address. Address ECH is read as BITR, written to CKCTLR.
2.The register PFDR only be implemented on devices, not on In-circuit Emulator.
