7.4.5 MSK0 to MSK4 - Mask interrupt registers
7.4.6 OUTCONF - output structure configuration register
These registers mask the interrupt due to a change in the I/O pins configured as inputs. ‘x’
refers to the bank number (0 to 4); ‘y’ refers to the bit number (0 to 7).
Table 9.
This register controls the configuration of the output ports as open-drain or totem-pole.
The 4 least significant bits control the output architecture for bank 0, 2 bits at a time.
The 4 most significant bits control the output architectures for bank 1 to bank 4, each bit
controlling one bank.
OUTx = 0: The I/Os are configured with an open-drain structure.
OUTx = 1: The I/Os are configured with a totem-pole structure.

Default
Mx[y] = 0: A level change at the I/O will generate an interrupt if IOx_y defined as input
(Cx[y] in IOC register = 1).
Mx[y] = 1: A level change in the input port will not generate an interrupt if IOx_y defined
as input (Cx[y] in IOC register = 1).
OUT001 controls the output structure for IO0_0 and IO0_1
OUT023 controls the output structure for IO0_2 and IO0_3
OUT045 controls the output structure for IO0_4 and IO0_5
OUT067 controls the output structure for IO0_6 and IO0_7
OUT1 controls the output structure for bank 1 (IO1_0 to IO1_7)
OUT2 controls the output structure for bank 2 (IO2_0 to IO2_7)
OUT3 controls the output structure for bank 3 (IO3_0 to IO3_7)
OUT4 controls the output structure for bank 4 (IO4_0 to IO4_7)
