EBI_nWRL_EN
Bits EBI_nWRL_EN (ALT_MFP[13]), EBI_EN (ALT_MFP[11]), PB2_TM2 (ALT_MFP2[4])
,
PB2_T2EX (ALT_MFP[26]) and GPB_MFP[2] determine the PB.2 function.

mapping is as following list.
(0, 0, 0 , 0, 0) = GPIO function is selected.
(0, 0, 0, 0, 1) = UART0_nRTS function is selected.
(0, 0, 0, 1, 1) = TM2_EXT function is selected.
(0, 0, 1, 0, 1) = TM2 function is selected.
(1, 1, 0, 0, 1) = nWRL(EBI) function is selected.

EBI_MCLK_EN
Bits EBI_MCLK_EN (ALT_MFP[12]), EBI_EN (ALT_MFP[11]), GPC_MFP[8] determine
the PC.8 function.
(EBI_MCLK_EN, EBI_EN, GPC_MFP8) value and function mapping is as following list.
(0, 0, 0) = GPIO function is selected to the pin PC.8.
(0, 0 ,1) = SPI1_SS0 function is selected to the pin PC.8.

[11]
EBI_EN
EBI_EN is use to switch GPIO function to EBI function (AD[15:0], ALE, RE, WE, CS,
MCLK), it need additional registers EBI_EN[7:0] and EBI_MCLK_EN for some GPIO to
switch to EBI function(AD[15:8], MCLK)
