analog pin MUX & globals
I'm wondering what should be the right register( PORT4_MUX and PORT4_AG) value in case when 4 pins are configured as analog and other 4 are untouched.
presuming ports configured P4.4 P4.5 P4.6 P4.7 the right value for port4_MUX or port4_AG should be 0xF0 (upper nibble full of ones, lower nibble - zeros)
But in fact PORT4_MUX = 0x4C and PORT4_AG=0x4D
Does it make sense?
