5.0
The SX device has three registers (FUSE, FUSEX,
DEVICE) that control functions such as operating the
device in Turbo mode, extended (8-level deep) stack
operation, and speed selection for the internal RC oscilla-
tor. These registers are not programmable “on the fly”
5.1
FUSE Word (Read/Program at FFFh in main memory map)
DEVICE CONFIGURATION REGISTERS
during normal device operation. Instead, the FUSE and
FUSEX registers can only be accessed when the SX
device is being programmed. The DEVICE register is a
read-only, hard-wired register, programmed during the
manufacturing process.

TURBO
Turbo mode enable:
0 =
turbo (instruction clock = osc/1)
1 =
instr clock = osc/4
Synchronous input enable (for turbo mode): This bit synchronizes the signal presented at the input pin
to the internal clock through two internal flip-flops.
0 =
enabled
1 =
disabled
Internal RC oscillator enable:
0 =
enabled - OSC1 pulled low by weak pullup, OSC2 pulled high by weak pullup
1 =
disabled - OSC1 and OSC2 behave according to FOSC2: FOSC0
Internal RC oscillator divider:
00b
=
4 MHz
01b
=
1 MHz
10
=
128 KHz
11b
=
32 KHz
Internal crystal/resonator oscillator feedback resistor:
0=
disabled
Internal feedback resistor disable (external feedback required)
1=
enabled
Internal feedback resistor enabled (valid when IRC = 1)
Code protect enable:
0 =
enabled (FUSE, code, and ID memories read back as garbled data)
1 =
disabled (FUSE, code, and ID memories can be read normally)
Watchdog timer enable:
0 =
disabled
1 =
enabled
FOSC2: FOSC0 External oscillator configuration (valid when IRC = 1):
000b =
LP1 – low power crystal (32KHz)
001b =
LP2 – low power crystal/resonator (32 KHz to 1 MHz)
010b =
XT1 – normal crystal/resonator (32 KHz to 10 MHz)
011b =
XT2 – normal crystal/resonator (1MHz to 24 MHz)
100b =
HS1 – high speed crystal/resonator (1MHz to 50 MHz)
101b =
HS2 – high speed crystal/resonator (1 MHz to 50 MHz)
110b =
HS3 – high speed crystal/resonator (1 MHz to 50 MHz)
111b =
RC network - OSC2 is pulled high with a weak pullup (no CLKOUT output)

The frequencies are target values.
