Does the S32K364 support the partial AB_SWAP mode?

你好！我手上有一块客户的S32K364板子，已经安装了AB_SWAP模式的HSE。读取DCMSTAT(0x402AC000)寄存器值为0x00040FF1，按手册代表DCMOTAA_EX这个位有效，芯片处于partial AB_SWAP模式，但是手册中又提到“This AB_SWAP mode is supported only for S32K328, S32K338, S32K348, S32K358, S32K356, S32K336, and S32K388”，请问这是一个doc bug还是什么原因？

For the S32K394, S32K374, and S32K364 devices, 0040_0000h is not available for IVT during AB-SWAP for boot loader but the ABSWAP function should be common feature
