Address:
When bit DDRBx is a logic 1, reading address $0001 reads the PTBx
data latch. When bit DDRBx is a logic 0, reading address $0001 reads
the voltage level on the pin. The data latch can always be written,
regardless of the state of its data direction bit.
the operation of the port B pins.
The PWM control register (PWMCR) selects the port B pins for PWM
function or as standard I/O function. (See

Notes:
Reset:
1. X = don’t care.
2. Hi-Z = high impedance.
3. Writing affects data register, but does not affect input.

Setting a PWMxE bit to logic 1 configures the PTBx/PWMx pin for
PWM output function. Reset clears the PWMxE bits.
