Peripheral Direct Memory Access
Table 31-2.
The clock for the CAT module, CLK_CAT, is generated by the Power Manager (PM). This clock
is turned on by default, and can be enabled and disabled in the PM. The user must ensure that
CLK_CAT is enabled before using the CAT module.
QMatrix operations also require the CAT generic clock, GCLK_CAT. This generic clock is gener-
ated by the System Control Interface (SCIF), and is shared between the CAT and the Analog
Comparator Interface. The user must ensure that the GCLK_CAT is enabled in the SCIF before
using QMatrix functionality in the CAT module. For proper QMatrix operation, the frequency of
GCLK_CAT must be less than half the frequency of CLK_CAT. If only QTouch functionality is
used, then GCLK_CAT is unnecessary.
The CAT interrupt request line is connected to the interrupt controller. Using CAT interrupts
requires the interrupt controller to be programmed first.
The CAT peripheral events are connected via the Peripheral Event System. Refer to the Periph-
eral Event System chapter for details.
The CAT module provides handshake capability for a Peripheral DMA Controller. One hand-
shake controls transfers from the Acquired Count Register (ACOUNT) to memory. A second
handshake requests burst lengths for each (X,Y) pair to the Matrix Burst Length Register
