Operating Modes and Resource Mapping
5.4.2 Register Initialization Register
After reset, the 512-byte register block resides at location $0000 but can be reassigned to any 2-Kbyte
boundary within the standard 64-Kbyte address space. Mapping of internal registers is controlled by five
bits in the register initialization register (INITRG). The register block occupies the first 512 bytes of the
2-Kbyte block.
Read: Anytime
Write: Once in normal modes; anytime in special modes
REG15–REG11 — Register Position Bits
MMSWAI — Memory Mapping Interface Stop in Wait Control Bit
5.4.3 RAM Initialization Register
After reset, addresses of the 1-Kbyte RAM array begin at location $0800 but can be assigned to any
2-Kbyte boundary within the standard 64-Kbyte address space. Mapping of internal RAM is controlled by
five bits in the RAM initialization register (INITRM). The RAM array occupies the first 1 Kbyte of the
2-Kbyte block.
Read: Anytime
Write: Once in normal modes; anytime in special modes
RAM15–RAM11 — RAM Position Bits
80
These bits specify the upper five bits of the 16-bit register address.
This bit controls access to the memory mapping interface when in wait mode.
Normal modes: Write anytime
Special modes: Write never
These bits specify the upper five bits of the 16-bit RAM address.
0 = Memory mapping interface continues to function in wait mode.
1 = Memory mapping interface access shuts down in wait mode.
