Register Description
MCUCR – MCU Control Register
PORTB – Port B Data Register
DDRB – Port B Data Direction Register
Table 10-5.
• Bits 7, 2 – Res: Reserved Bits
These bits are reserved bits in the ATtiny13A and will always read as zero.
• Bit 6 – PUD: Pull-up Disable
When this bit is written to one, the pull-ups in the I/O ports are disabled even if the DDxn and
PORTxn Registers are configured to enable the pull-ups ({DDxn, PORTxn} = 0b01). See
