Table 9-3 Control Registers of GMS81C1404 and GMS81C1408
These registers of shaded area can not be accessed by bit manipulation instruction as “SET1, CLR1”, but should be accessed by
register 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.
