2080 TO 2081 (0x0820 TO 0x0821)—MULTIPURPOSE PIN CONFIGURATION REGISTERS
Each multipurpose pin can be set to different functions from
these registers (2080 to 2081). The two 3-byte registers are
broken up into 12 4-bit (nibble) sections that each control a
different MP pin. Table 55 lists the function of each nibble
setting within the MP pin configuration registers. The MSB of
Rev. 0 | Page 41 of 52
each pin’s 4-bit configuration inverts the input to or output
from the pin. The internal pull-up resistor (approximately
10 kΩ) of each MP pin is enabled when it is set as a digital input
(either a GPIO input or a serial data port input).
