7. PSIF TXEN/RXEN may disable the transmitter/receiver
8. PSIF TXRDY interrupt corrupts transfers
9. PWMcounter restarts at 0x0001
10. PWM channel interrupt enabling triggers an interrupt
11. PWM update period to a 0 value does not work
12. PWM channel status may be wrong if disabled before a period has elapsed
13. TWI transfer error without ACK
Fix/Workaround
Use slot A.
Writing a '0' to RXEN will disable the receiver. Writing '0' to TXEN will disable the transmitter.
Fix/Workaround
When accessing the PS/2 Control Register always write '1' to RXEN to keep the receiver
enabled, and write '1' to TXEN to keep the transmitter enabled.
When writing to the Transmit Holding Register (THR), the data will be transferred to the data
shift register immediately, regardless of the state of the data shift register. If a transfer is
ongoing, it will be interrupted and a new transfer will be started with the new data written to
THR.
Fix/Workaround
Use the TXEMPTY-interrupt instead of the TXRDY-interrupt to update the THR. This
ensures that a transfer is completed.
The PWM counter restarts at 0x0001 and not 0x0000 as specified. Because of this the first
PWM period has one more clock cycle.
Fix/Workaround
- The first period is 0x0000, 0x0001, ..., period
- Consecutive periods are 0x0001, 0x0002, ..., period
When enabling a PWM channel that is configured with center aligned period (CALG=1), an
interrupt is signalled.
Fix/Workaround
When using center aligned mode, enable the channel and read the status before channel
interrupt is enabled.
It is impossible to update a period equal to 0 by the using the PWM update register
(PWM_CUPD).
Fix/Workaround
Do not update the PWM_CUPD register with a value equal to 0.
Before a PWM period has elapsed, the read channel status may be wrong. The CHIDx-bit
for a PWM channel in the PWM Enable Register will read '1' for one full PWM period even if
the channel was disabled before the period elapsed. It will then read '0' as expected.
Fix/Workaround
Reading the PWM channel status of a disabled channel is only correct after a PWM period
