NOTE:
T1CH[1:0] — Timer 1 Channel I/O Bits
T2CH[1:0] — Timer 2 Channel I/O Bits
ADC[5:4] — ADC Channels 5 and 4
Care must be taken when reading port B while applying analog voltages
to ADC[5:4] pins. If the appropriate ADC channel is not enabled,
excessive current drain may occur if analog voltages are applied to the
PTBx/ADCx pin, while PTB is read as a digital input. Those ports not
selected as analog input channels are considered digital I/O ports.
LED Drive — Direct LED Drive Pins
The T1CH1 and T1CH0 pins are the TIM1 input capture/output
compare pins. The edge/level select bits, ELSxB:ELSxA, determine
whether the PTB2/T1CH0 and PTB3/T1CH1 pins are timer channel
I/O pins or general-purpose I/O pins. See
Interface Module
The T2CH1 and T2CH0 pins are the TIM1 input capture/output
compare pins. The edge/level select bits, ELSxB:ELSxA, determine
whether the PTB4/T2CH0 and PTB5/T2CH1 pins are timer channel
I/O pins or general-purpose I/O pins. See
Interface Module
ADC[5:4] are pins used for the input channels to the analog-to-digital
converter module. The channel select bits, ADCH[4:0], in the ADC
status and control register define which port pin will be used as an
ADC input and overrides any control from the port I/O logic. See
Section 16. Analog-to-Digital Converter
PTB0–PTB5 pins can be configured for direct LED drive. See
