Note 1: The P70 and P71 pins do not have pull-ups.
Note 2: The pin for which this bit is "1" (pulled high) and the direction bit is "0" (input mode) is pulled high.
Note 3: The values after hardware reset are as follows:
• 00000000 2 when input on CNVss pin is "L"
The values after software reset and watchdog timer reset are as follows:
• 00000000 2 when PM 01 to PM00 bits of PM0 register are "002" (single-chip mode)

Nothing is assigned. In an attempt to write to these bits, write
"0". The value, if read, turns out to be "0".
Note 1: The pin for which this bit is "1" (pulled high) and the direction bit is "0" (input mode) is pulled high.
Note 2: The P85 pin does not have pull-up.
