CC430 IO Remapping的问题

那您的意思，P2.6和P2.7，不能Remapping成 

P2SEL |= BIT6 + BIT7; 
PMAPPWD = 0x02D52; // Get write-access to port mapping regs

P2MAP6 = PM_UCB0SDA; // Map UCB0SDA output to P2.6
P2MAP7 = PM_UCB0SCL; // Map UCB0SCL output to P2.7
PMAPPWD = 0; // Lock port mapping registers

请问 您的依据是从哪里来的，手册中有说明吗？
