14 ST72324J/K DEVICE CONFIGURATION AND ORDERING INFORMATION
Each device is available for production in user pro-
grammable versions (FLASH) as well as in factory
coded versions (ROM). FLASH devices are
shipped to customers with a default content (FFh),
while ROM factory coded parts contain the code
supplied by the customer. This implies that FLASH
devices have to be configured by the customer us-
ing the Option Bytes while the ROM devices are
factory-configured.
14.1 FLASH OPTION BYTES
The option bytes allows the hardware configura-
tion of the microcontroller to be selected. They
have no address in the memory map and can be
accessed only in programming mode (for example
using a standard ST7 programming tool). The de-
fault content of the FLASH is fixed to FFh. To pro-
gram directly the FLASH devices using ICP,
FLASH devices are shipped to customers with the
internal RC clock source. In masked ROM devic-
es, the option bytes are fixed in hardware by the
ROM code (see option list).
OPT15= PKG32P
32 Pin package selection
This option bit selects the 32 pin package.
Non-bonded pins in small packages are pulled-up
and then after RESET the floating configure is sta-
ble. Warning, when not bonded, this pin must keep
the input floating configuration to avoid added cur-
rent consumption and to be compatible with sub-
set devices.
OPT14 = RSTC
RESET clock cycle selection
This option bit selects the number of CPU cycles
applied during the RESET phase and when exiting
HALT mode. For resonator oscillators, it is advised
to select 4096 due to the long crystal stabilization
time.
0: Reset phase with 4096 CPU cycles
1: Reset phase with 256 CPU cycles
Note: when the CSS is enabled, the device starts
to count immediately thanks to the backup oscilla-
tor.
OPT13:12 = OSCTYPE[1:0]
Oscillator Type
These option bits select the ST7 main clock
source type.
OPT11:9 = OSCRANGE[2:0]
Oscillator range
When the resonator oscillator type is selected,
these option bits select the resonator oscillator
current source corresponding to the frequency
range of the used resonator. Otherwise, these bits
are used to select the normal operating frequency
range (see CSS option description).
