7.4.7.1 Examples
7.4.7 ALLBNK - All Bank control register
Table 10.
This register allows all the I/Os configured as outputs to be programmed with the same
logic value. This programming is applied to all the banks or a selection of banks.
When this register is programmed, values in the Output Port registers are not changed
and do not reflect the states of I/Os configured as outputs anymore.

B0 to B4 controls the logic level to be applied to Bank 0 to Bank 4, respectively.
– Bx = 0: All the I/Os configured as outputs in the corresponding Bank x are
– Bx = 1: All the I/Os configured as outputs in the corresponding Bank x are
Bit 5 and bit 6 are not used and can be programmed to either ‘1’ or ‘0’.
BSEL is a filter bit that allows programming of some banks only, and not the others.
– BSEL = 0:
– BSEL = 1:
If ALLBNK = 0XX0 0000:
All I/Os configured as outputs in Bank 0 to Bank 4 will be programmed with 0s,
overwriting values programmed in the five Output Port registers.
If ALLBNK = 1XX1 1111:
All I/Os configured as outputs in Bank 0 to Bank 4 will be programmed with 1s,
overwriting values programmed in the five Output Port registers.
If ALLBNK = 0XX0 0110:
All I/Os configured as outputs in Banks 0, 3, and 4 only will be programmed with 0s,
overwriting values programmed in the Output Port registers 0, 3, and 4, while I/Os
configured as outputs in Bank 1 and Bank 2 are programmed with values in Output
Port registers 1 and 2.

programmed with 1s.
When Bx = 0, all the I/Os configured as output in the corresponding Bank x are
programmed with 0s.
When Bx = 1, all the I/Os configured as output in the corresponding Bank x are
programmed with their actual value from the corresponding output register.
When Bx = 0, all the I/Os configured as output in the corresponding Bank x are
programmed with their actual value from the corresponding output register.
When Bx = 1, all the I/Os configured as output in the corresponding Bank x are
programmed with 1s.
