Register Description
PORTCR – Port Control Register
PUEB – Port B Pull-up Enable Control Register
Table 10-5.
Notes:
• Bits 7:2, 0 – Reserved
These bits are reserved and will always read zero.
• Bit 1 – BBMB: Break-Before-Make Mode Enable
When this bit is set the Break-Before-Make mode is activated for the entire Port B. The interme-
diate tri-state cycle is then inserted when writing DDRxn to make an output. For further
