System Registers
Register: 0xFF0B
Multipurpose I/O Bank 0 Latch Mask (MPLM0)
Read/Write
MPLM0_[7:0] Multipurpose I/O Bank 0 Latch Mask
[7:0]
These read/write register bits define the write mask for
the
Multipurpose I/O Bank 0 Latch (MPL0)
register
). A value of 1 in any of these bits allows the
corresponding bit in the MPL0 to be modified.
Register: 0xFF0C
Multipurpose I/O Bank 0 Latch (MPL0)
Read/Write
MPL0_[7:0]
Multipurpose I/O Bank 0 Latch
[7:0]
These read/write register bits store the power-on value of
the I/O pins MPIO0_0, MPIO0_1, MPIO0_2, MPIO0_3,
MPIO0_4, MPIO0_5, MPIO0_6, and MPIO0_7. The
values on these pins are latched into this register on the
deasserting edge of the RESET/ input signal or the
internal power-on reset.
