Table 10-9. Overriding Signals for Alternate Functions in PB[1:0]
Note:
When TWI is enabled the slew rate control and spike filter are activate on PB1. This is not illustrated in Figure 10-6 on
page 48. The spike filter is connected between AIOxn and the TWI.

Register Description
10.4.1 PORTCR – Port Control Register
Bits 7:2 – Res: Reserved Bits
These bits are reserved and will always read as 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 intermediate tri-state cycle is then
inserted when writing DDRBn to make an output. For further information, see “Break-Before-Make Switching” on page
Bit 0 – BBMA: Break-Before-Make Mode Enable
When this bit is set the Break-Before-Make mode is activated for the entire Port A. The intermediate tri-state cycle is then
inserted when writing DDRAn to make an output. For further information, see “Break-Before-Make Switching” on page
