GLOC
aWire
8. CAT QMatrix sense capacitors discharged prematurely
1. GLOC is non-functional
1. aWire PB mapping and PB clock mask number
2. SAB multiaccess reads are not working
3. If a reset happens during the last SAB write, the aWire will stall
4. aWire enable does not work in Static mode
5. VERSION register reads 0x200
At the end of a QMatrix burst charging sequence that uses different burst count values for
different Y lines, the Y lines may be incorrectly grounded for up to n-1 periods of the periph-
eral bus clock, where n is the ratio of the PB clock frequency to the GCLK_CAT frequency.
This results in premature loss of charge from the sense capacitors and thus increased vari-
ability of the acquired count values. For example, if the PB clock frequency is 24MHz and
GCLK_CAT frequency is 6 MHz, n=4 and the Y lines may be incorrectly grounded for 0, 1, 2,
or 3 periods of the PB clock, depending on the relative phase of the PB and GCLK_CAT
clocks.
Fix/Workaround
Enable the 1kOhm drive resistors on all implemented QMatrix Y lines (CSA 1, 3, 5, 7, 9, 11,
and/or 15) by writing ones to the corresponding odd bits of the CSARES register. For exam-
ple, if all 8 Y lines are implemented, write 0x0000AAAA to the CSARES register. When the Y
lines are incorrectly grounded by the CAT module for up to n-1 PB clocks at the end of burst
charging sequence, this will greatly reduce the amount of charge that is prematurely lost
from the sense capacitors, because the discharge time constant will now be approximately
1000Ohm times the value of the of the sense capacitor instead of a very small resistance
times the value of the sense capacitor.
Glue Logic Controller (GLOC) is non-functional.
Fix/Workaround
None.
The aWire PB has a different PB address and PB clock mask number.
Fix/Workaround
Use aWire PB address 0xFFFF6C00 and PB clock (PBAMASK) 24.
Reading more than one word, halfword, or byte in one command is not working correctly.
Fix/Workaround
Split the access into several single word, halfword, or byte accesses.
If a reset happens during the last word, halfword, or byte write the aWire will wait forever for
an acknowledge from the SAB.
Fix/Workaround
Reset the aWire by keeping the RESET_N line low for 100ms.
aWire enable does not work in Static mode.
Fix/Workaround
None.
The VERSION register reads 0x200 instead of 0x210.
Fix/Workaround
None.
