Product data sheet
7.6.6 Register 5 - Bus-hold/pull-up/pull-down enable 1 register
Bit 0 of this register allows the user to enable/disable the bus-hold feature for the I/O pins.
Setting the bit 0 to logic 1 enables bus-hold feature for the I/O bank 1. In this mode, the
pull-up/pull-downs will be disabled for I/O bank 1. Setting the bit 0 to logic 0 disables
bus-hold feature.
Bit 1 of this register allows the user to enable/disable pull-up/pull-downs on the I/O pins.
Setting the bit 1 to logic 1 enables selection of pull-up/pull-down using Register 7. Setting
the bit 1 to logic 0 disables pull-up/pull-downs on the I/O bank 1 pins and contents of
Register 7 will have no effect on the I/O.
