bank can consist of up to 16 wordwide (R0 to R15) and/or bytewide (RL0, RH0, …, RL7,
RH7) so-called General Purpose Registers (GPRs).
The upper 256 bytes of the DPRAM are directly bitaddressable. When used by a GPR,
any location in the DPRAM is bitaddressable.
1024 bytes (2
× 512 bytes) of the address space are reserved for the Special Function
Register areas (SFR space and ESFR space). SFRs are wordwide 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.
In order to meet the needs of designs where more memory is required than is provided
on chip, up to 12 Mbytes (approximately, see Table 3) of external RAM and/or ROM can
be connected to the microcontroller.
