AtTiny 861 (a) some port pins not working <SOLVED>

[jdwaldron]

Using Arduino IDE 1.8.13 and current ATinyCore.
Simple sketch to just toggle all port pins high and low.
Works on ports 0,1,2 (PortA 0,1,2), nothing on the rest of the port pins (3 - 15).
I assume (really going out on a limb here) that it's some sort of mapping problem.
I'm happy to help resolve if this is a real problem (and not just me). Not sure if my skill set is up to the task though, but happy to be part of the solution.

(FWIW - same result on Arduino IDE 2.0.4)

Oops - looks like my ATTinyCore is version 1.5.2
(I don't seem to be able to find 2.0.0 in the Boards Manager)

(Here's the sketch - just in case)

void setup() {
 
  pinMode(0, OUTPUT);
  pinMode(1, OUTPUT);
  pinMode(2, OUTPUT);  
  pinMode(14, OUTPUT);
  pinMode(10, OUTPUT); 
  pinMode(11, OUTPUT);  
  pinMode(12, OUTPUT); 
  pinMode(13, OUTPUT);

}

void loop() {
  digitalWrite(0, HIGH);  // turn the LED on (HIGH is the voltage level)
  delay(50);                      // wait 
  digitalWrite(0, LOW);   // turn the LED off by making the voltage LOW
  delay(50);                      // wait
  
  digitalWrite(0, HIGH);  // turn the LED on (HIGH is the voltage level)
  delay(50);                      // wait 
  digitalWrite(0, LOW);   // turn the LED off by making the voltage LOW
  delay(50);  
 
  digitalWrite(0, HIGH);  // turn the LED on (HIGH is the voltage level)
  delay(50);                      // wait 
  digitalWrite(0, LOW);   // turn the LED off by making the voltage LOW
  delay(200);  
  
  
  digitalWrite(1, HIGH);  // turn the LED on (HIGH is the voltage level)
  delay(50);                      // wait 
  digitalWrite(1, LOW);   // turn the LED off by making the voltage LOW
  delay(50);                      // wait 
  
  digitalWrite(1, HIGH);  // turn the LED on (HIGH is the voltage level)
  delay(50);                      // wait 
  digitalWrite(1, LOW);   // turn the LED off by making the voltage LOW
  delay(50);  
 
  digitalWrite(1, HIGH);  // turn the LED on (HIGH is the voltage level)
  delay(50);                      // wait 
  digitalWrite(1, LOW);   // turn the LED off by making the voltage LOW
  delay(200);  
  
  digitalWrite(2, HIGH);  //etc.
  delay(50);                 
  digitalWrite(2, LOW);   
  delay(200);  
  
  digitalWrite(14, HIGH);  
  delay(50);                 
  digitalWrite(14, LOW);   
  delay(200); 
  
  digitalWrite(10, HIGH);  
  delay(50);                 
  digitalWrite(10, LOW);   
  delay(200); 
  
  digitalWrite(11, HIGH);  
  delay(50);                 
  digitalWrite(11, LOW);   
  delay(200); 
       
  digitalWrite(12, HIGH);  
  delay(50);                 
  digitalWrite(12, LOW);   
  delay(50);  
  
  digitalWrite(12, HIGH);  
  delay(50);                 
  digitalWrite(12, LOW);   
  delay(50); 
     
  digitalWrite(13, HIGH);  
  delay(50);                 
  digitalWrite(13, LOW);   
  delay(50);  
  
  digitalWrite(13, HIGH);  
  delay(50);                 
  digitalWrite(13, LOW);   
  delay(50);  
  
    delay(500);                    
}

And, (also just in case),
AtTiny861a, 16Mhz crystal (on programmer board (Arduino ISP fed), and test board). 16Mhz external selected.
Board ATtinyCore -ATtiny261/461/861(a) selected
Chip ATtiny861(a)
Clock source 16Mhz (external)
Programmer Arduino as ISP
I don't think the problem is here as it runs, toggling the first 3 pins (0,1, and 2) physical pins 20, 19, 18.
No activity on any other pins - all other port pins are hi-Z

Looks like the problem was me. Trying to use the Reset pin as an input without setting the requisite registers. Many apologies for suggesting the library had a problem.
