AT91RM9200
Table 10-6.
• Each channel is user-configurable and contains:
• Internal interrupt signal
• Two global registers that act on all three TC Channels
• The Timer Counter 0 to 5 are described with five generic clock inputs, TIMER_CLOCK1 to
• Compatibility with MultiMedia Card Specification Version 2.2
• Compatibility with SD Memory Card Specification Version 1.0
• Cards clock rate up to Master Clock divided by 2
• Embedded power management to slow down clock rate when not used
• Supports two slots
• Support for stream, block and multi-block data read and write
• Connection to a Peripheral DMA Controller (PDC) channel
TIMER_CLOCK5. In the AT91RM9200, these clock inputs are connected to the Master Clock
(MCK), to the Slow Clock (SLCK) and to divisions of the Master Clock. For details, see
