REGISTERS
The registers listed in Table 14-2 program the SSI. Appendix A summarizes the bits in all
the registers. For a complete description of all the peripheral registers, see the
Am186™CC/
CH/CU Microcontrollers Register Set Manual, order #21916.

Description
2F0h
SSSTAT
SSI Mode/Status
Defines SSI modes of operation and reports
the port status.
2F2h
SSCON
SSI Control
Enables SSI and programs the data order,
clock divisor, and polarity.
2F4h
SSTXD1
SSI Transmit 1
Contain the data to be transmitted. A write to
either register initiates a transmit transaction if
either of the DE bits in SSCON is set to 1.
2F6h
SSTXD0
SSI Transmit 0
2F8h
SSRXD
SSI Receive
Contains the data received over the SSI. A
read from this register initiates a receive
transaction if either of the DE bits in SSCON
is set to 1.
