MOTOROLA
CMOS Sensor Interface Module
The RxFIFO full level is programmed by the RxFF_LEVEL bits in CSI Control Register 1. When the
32-word RxFIFO is full, any further data writes to the RxFIFO by the external CMOS sensors are ignored
and the RxFIFO overrun interrupt (when enabled) is generated. The RxFIFO and STATFIFO operate
identically.
31.4.2 CSI Interrupt Operation
The CSI provides a single interrupt to the interrupt controller. For interrupt pin assignments, see
Chapter 10, “Interrupt Controller (AITC).”
31.4.3 Register Access When CSI Module is Disabled
The EN and MCLKDIV [3:0] bits of CSI Control Register 1 should be written during CSI module disable
mode (EN bit = 0) only.
Setting the EN bit to
0
causes all of the CSI module registers to initialize except for the EN and MCLKDIV
bits of CSI Control Register 1.
To initialize the CSI module registers for operation, perform the following steps:
•
Set the EN bit of CSI Control Register 1 to
1
.
•
Write values to other registers or other bits of CSI Control Register 1.
•
Complete remaining user-specified procedures.
31.5 Programming Model
The CSI module includes five user-accessible 32-bit registers. Table 31-4 summarizes these registers and
their addresses.
