The pin function is switched as shown below according to the combination of bit AMS in
EDMDR_2 of the EXDMAC, bit P84DDR, and bit ITS4 in ITSR.
Note: * Not supported by the H8S/2375, H8S/2375R, H8S/2373, and H8S/2373R.
Modes 1, 2, 4, 7 (EXPE = 1)
Mode 7 (EXPE = 0)
The pin function is switched as shown below according to the combination of bit ETENDE in
EDMDR_3 of the EXDMAC, bit RE in SCR of SCI_3, bit P83DDR, and bit ITS3 in ITSR.
Note: * Not supported by the H8S/2375, H8S/2375R, H8S/2373, and H8S/2373R.
Modes 1, 2, 4, 7 (EXPE = 1)
* IRQ4 input when ITS4 = 1.
* IRQ4 input when ITS4 = 1.
* IRQ3 input when ITS3 = 1.
