7# In microcomputer (MC) mode, the vectors are mapped into the on-chip ROM,
8# otherwise in microprocessor (MP) mode the vectors are mapped to address 0
9# on the external bus. In MC mode, the on-chip ROM contains a bootloader program
10# that loads the internal RAM from the serial port or external ROM.
11#
12# Common configurations:
13# 1. MC mode, no external memory (serial boot).
14# 2. MC mode, external RAM (serial boot).
15# 3. MC mode, external ROM.
16# 4. MC mode, external ROM, external RAM.
17# 5. MP mode, external ROM.
18# 6. MP mode, external ROM, external RAM.
19# 7. MP mode, external RAM (dual-port with hosting CPU or external debugger).
20#
21# Config TEXT DATA/BSS
22# 1. INT_RAM INT_RAM (mcmode,onchip)
23# 2. EXT_RAM EXT_RAM (mcmode,extram)
24# 3. INT_RAM INT_RAM (mcmode,onchip)
25# 4. EXT_RAM EXT_RAM (mcmode,extram)
26# 5. EXT_ROM INT_RAM (mpmode,onchip,extrom)
27# 6. EXT_ROM EXT_RAM (mpmode,extram,extrom)
28# 7. EXT_RAM EXT_RAM (mpmode,extram)
29#
6c19b93b 30# In MC mode, TEXT and DATA are copied into RAM by the bootloader.

SS
31#
32# In MP mode with external ROM, DATA needs to be copied into RAM at boot time.
33#
6c19b93b 34# If there is external RAM it is better to use that and reserve the internal RAM
0da35f8b
SS
35# for data buffers. However, the address of the external RAM needs to be specified.
36#
37# This emulation assumes config 7.
