OPERATING MODES AND ON-CHIP MEMORY
TECHNICAL DATA
4-11
RAM[3:0] — RAM Map Position
These four bits, which specify the upper hexadecimal digit of the RAM address, control
position of RAM in the memory map. RAM can be positioned at the beginning of any
4-Kbyte page in the memory map. Refer to Table 4-5.
REG[3:0] — 128-Byte Register Block Position
These four bits specify the upper hexadecimal digit of the address for the 128-byte
block of internal registers. The register block is positioned at the beginning of any 4-
Kbyte page in the memory map. Refer to Table 4-5.
When the memory map has the 96-byte register block mapped at the same location
as RAM, the registers have priority and the lower 96 bytes of RAM are inaccessible.
No harmful conicts occur due to a hardware resource priority scheme. On-chip reg-
isters have the highest priority of all on-chip resources, followed by on-chip RAM, boot-
strap ROM, and on-chip EEPROM.
4.3.2.3 OPTION Register
The 8-bit special-purpose OPTION register sets internal system configuration options
during initialization. In single-chip and expanded modes (SMOD = 0), IRQE, DLY, FC-
ME, and CR[1:0] can be written only once and only in the first 64 cycles after a reset.
This minimizes the possibility of any accidental changes to the system configuration.
In special test and bootstrap modes (SMOD = 1), these bits can be written at any time.
*Can be written only once in first 64 cycles out of reset in normal modes or at any time in special modes.
