• P84/EDACK2
*
/(IRQ4)
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)
AMS 0 1
P84DDR 0 1 ⎯
Pin function P84 input P84 input/output EDACK2 output
IRQ4 interrupt input
*
Note: * IRQ4 input when ITS4 = 1.
Mode 7 (EXPE = 0)
AMS ⎯
P84DDR 0 1
Pin function P84 input P84 output
IRQ4 interrupt input
*
Note: * IRQ4 input when ITS4 = 1.
• P83/ETEND3
*
/(IRQ3)/RXD3
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)
ETENDE 0 1
RE 0 1 ⎯
P83DDR 0 1 ⎯ ⎯
Pin function P83 input P83 output RXD3 output ETEND3 output
IRQ3 interrupt input
*
Note: * IRQ3 input when ITS3 = 1.
