+* DESCRIPTION:
+* Part of DRX driver.
+* Data access protocol: Fast Access Sequential Interface (fasi)
+* Fast access, because of short addressing format (16 instead of 32 bits addr)
+* Sequential, because of I2C.
+*
+* USAGE:
+* Include.

+/*
+* Comments about short/long addressing format:
+*
+* The DAP FASI offers long address format (4 bytes) and short address format
+* (2 bytes). The DAP can operate in 3 modes:
+* (1) only short
+* (2) only long
+* (3) both long and short but short preferred and long only when necesarry
+*
+* These modes must be selected compile time via compile switches.
+* Compile switch settings for the diffrent modes:
+* (1) DRXDAPFASI_LONG_ADDR_ALLOWED=0, DRXDAPFASI_SHORT_ADDR_ALLOWED=1
+* (2) DRXDAPFASI_LONG_ADDR_ALLOWED=1, DRXDAPFASI_SHORT_ADDR_ALLOWED=0
+* (3) DRXDAPFASI_LONG_ADDR_ALLOWED=1, DRXDAPFASI_SHORT_ADDR_ALLOWED=1
+*
+* The default setting will be (3) both long and short.
+* The default setting will need no compile switches.
+* The default setting must be overridden if compile switches are already
+* defined.

+* Comments about SINGLE MASTER/MULTI MASTER modes:

+* Consider the two sides:1) the master and 2)the slave.
+*
+* Master:
+* Single/multimaster operation set via DRXDAP_SINGLE_MASTER compile switch
+* + single master mode means no use of repeated starts
+* + multi master mode means use of repeated starts
+* Default is single master.
+* Default can be overriden by setting the compile switch DRXDAP_SINGLE_MASTER.
+*
+* Slave:
+* Single/multi master selected via the flags in the FASI protocol.
+* + single master means remember memory address between i2c packets
+* + multimaster means flush memory address between i2c packets
+* Default is single master, DAP FASI changes multi-master setting silently
+* into single master setting. This cannot be overrriden.

+********************************************/
+/*
+* Comments about DRXDAP_MAX_WCHUNKSIZE in single or multi master mode and
+* in combination with short and long addressing format. All text below
+* assumes long addressing format. The table also includes information
+* for short ADDRessing format.
+*
+* In single master mode, data can be written by sending the register address
+* first, then two or four bytes of data in the next packet.
+* Because the device address plus a register address equals five bytes,
+* the mimimum chunk size must be five.
+* If ten-bit I2C device addresses are used, the minimum chunk size must be six,
+* because the I2C device address will then occupy two bytes when writing.
+*
+* Data in single master mode is transferred as follows:
+* <S> <devW> a0 a1 a2 a3 <P>
+* <S> <devW> d0 d1 [d2 d3] <P>
+* ..
+* or
+* ..
+* <S> <devW> a0 a1 a2 a3 <P>
+* <S> <devR> --- <P>
+*
+* In multi-master mode, the data must immediately follow the address (an I2C
+* stop resets the internal address), and hence the minimum chunk size is
+* 1 <I2C address> + 4 (register address) + 2 (data to send) = 7 bytes (8 if
+* 10-bit I2C device addresses are used).
+*
+* The 7-bit or 10-bit i2c address parameters is a runtime parameter.
+* The other parameters can be limited via compile time switches.
