XC164SM
Derivatives
Functional Description
can consist of up to 16 word wide (R0 to R15) and/or byte wide (RL0, RH0, â¦, RL7, RH7)
so-called General Purpose Registers (GPRs).
The upper 256 bytes of the DPRAM are directly bit addressable. When used by a GPR,
any location in the DPRAM is bit addressable.
1024 bytes (2 Ã 512 bytes) of the address space are reserved for the Special Function
Register areas (SFR space and ESFR space). SFRs are word wide registers which are
used for controlling and monitoring functions of the different on-chip units. Unused SFR
addresses are reserved for future members of the XC166 Family. Therefore, they should
either not be accessed, or written with zeros, to ensure upward compatibility.

1) The areas marked with â<â are slightly smaller than indicated, see column âNotesâ.
2) Not defined register locations return a trap code (1E9BH).
3) Depends on the respective derivative. See Table 1 âXC164SM Derivative Synopsisâ on Page 6.
