Register CRPR1 contains bits that request a conversion of the corresponding analog
channel. The bits in this register have only a read view. A write operation to this address
leads to a data write to CRCR1 with an automatic load event one clock cycle later.
Note: The bits that can be read from this register location are generally ‘rh’. They cannot
be modified directly by a write operation. A write operation modifies the bits in
CRCR1 (that is why they are marked ‘rwh’) and leads to a load event one clock
cycle later.

Channel Pending Bit x
Write view:
A write to this address targets the bits in register
CRCR1.
Read view:
Each bit corresponds to one analog channel; the
channel number x is defined by the bit position in the
register.
The arbiter automatically resets (at start of
conversion) or sets it again (at abort of conversion)
for the corresponding analog channel.
0
B
The analog channel x is not requested for
conversion by the parallel request source.
1
B
The analog channel x is requested for
conversion by the parallel request source.

Returns 0 if read; should be written with 0.
