MPC821/MPC823 IDMA Driver
The IDMA driver provides an initialization example and starts an IDMA
transfer on the MPC821FADS system in the following modes:
memory-to-memory, memory-to-peripheral, single address fly-by, and burst
address fly-by. Special downloadable microcode routines are also included.
Note: Use "pkzip -d" to unbundle. (02/19/97)

MPC821/MPC823 MMU & Cache Driver
The MMU and cache driver initializes the cache and MMU registers. It then
dynamically maps regions for DRAM, FLASH, and internal I/O registers using
the standard two-level segment and page descriptor tables. The virtual address
of each region is mapped one-to-one to a physical address with page attributes
that allow memory areas to be cacheable, cache-inhibited, or write-protected.
Now includes fix for CPU2 errata. (09/15/98)

MPC821/MPC823 MMU Lite Driver
Initializes the cache and MMU registers. Statically maps entire regions of
DRAM, FLASH, and internal I/O registers by preloading the translation
lookaside buffers with large page-size entries. This prevents TLB-miss
exceptions that could degrade the performance of your system. The virtual
address of each region is mapped one-to-one to a physical address with large
page attributes that allow memory areas to be cacheable, cache-inhibited, or
write-protected. This driver is perfect for benchmarking, but it can also be used
in small systems that do not have a demand page memory allocation scheme.
Requires very little memory.
The MMU Lite executable, a README file, and source code is in a pkzip
archive. The MPC8Bug monitor debugger is used to download the MMU Lite
executable. (02/26/96)

MPC821/MPC823 Real-Time Clock (RTC) Driver
Operates the real-time clock (RTC). Can be configured to register an RTC
interrupt once per second (per-second mode). Alternatively, can configure the
interrupt period of the driver to be a 32-bit programmable value in units of
seconds (alarm mode). Will light the ETH ON LED on the MPC821FADS
system to indicate an RTC interrupt. (09/02/1997)

MPC821/MPC823 UART Driver (SCCx Interrupt)
The SCCx UART driver supports internal loopback and two external loopback
operating modes that you configure. This driver allows you to select the SCC
that you want to use for UART. It also processes the SCC2 UART receive
interrupt. (09/16/97)

MPC821/MPC823 UART Driver (SMC2 Polling)
The SMC2 UART driver sets up SMC2 for UART communication. It then
verifies the setup by performing a put, a get, and a poll for a single character.
To use this code with the MPC821FADS, you must physically connect the
SMC2 transmission and reception pins. The PKZIP archive contains the
driver's source code and object files. (09/02/97)

MPC821/MPC823 SPI Internal Loopback Driver
The SPI Loopback Driver transmits and receives a single character that is 4 to
16 bits long and then it verifies the transmission. The driver operates in internal
loopback mode. The character length (4..16 bits) and interrupt level (0..7) are
both programmable. The SPI Loopback Driver processes the SPI receive
interrupt. (09/02/97)

MPC821/MPC823 SPI TouchPanel Driver
Uses the on-chip SPI controller to communicate with the DynaPro DTFP95617
touch panel through a MAXIM MAX192 Analog/Digital converter. The touch
event is processed as an IRQ1 interrupt. A pair of XY coordinates are received
as 10-bit values from the A/D converter. The two sub-LSBs provided by the
A/D converter are discarded and no scaling or calibration of the coordinates is
performed. The SPI controller operates in master mode with 8-bit character
length. A schematic of the touch panel interface to the MPC821 is included in
the PKZIP archive. (09/02/97)
