PRELIMINARY DATA SHEET
31. Hardware Options
31.1. Functional Description
Hardware Options are available in several areas to adapt the
IC function to the host system requirements:
– clock signal selection for most of the peripheral modules
from f
on page 206)
– Special Out signal selection for some U- and H-ports
– Rx/Tx polarity selection for SPI and UART modules
Hardware Option setting requires two steps:
1. selection is done by programming dedicated address loca-
tions in the HW Options field (see Section 31.2. on
page 205) with the desired options’ code (see Section 31.3.
on page 206).
2. activation is done by copying the HW Options field to the
31.2. Listing of Dedicated Addresses of the Hardware Options Field
Please refer to section “Memory and Boot System” for the
dedicated start address of the HW Options field.

corresponding HW Options registers (see Section 31.3. on
page 206) at least once after each reset.
In EMU and MCM devices all HW Options are SW progam-
mable.
In mask ROM derivatives the clock options are hard wired
according to the HW Options field of the ROM code hex file.
Those options can only be altered by changing a production
mask.
To ensure compatible option settings in MCM and mask
ROM derivatives, when run with the same ROM code, it is
mandatory to always write the HW Options field to the HW
option registers directly after reset.
