2. PWM not Phase Correct
1. TWI is Speed Limited in Slave Mode
Problem Fix/Workaround
Ensure at least one instruction (e.g., nop) is executed between two writes to TWCR.
In Phase-correct PWM mode, a change from OCRx = TOP to anything less than
TOP does not change the OCx output. This gives a phase error in the following
period.
Problem Fix/Workaround
Make sure this issue is not harmful to the application.
When the two-wire Serial Interface operates in Slave mode, frames may be unde-
tected if the CPU frequency is less than 64 times the bus frequency.
Problem Fix/Workaround
Ensure that the CPU frequency is at least 64 times the TWI bus frequency.
