Note: *

UCAS output depending on bits DRAS2 to DRAS0 in DRCRA and bit

CSEL in DRCRB, and regardless of bits NDER12 and PB4DDR. For

details, see section 6, Bus Controller.

The DRAM interface settings by bits DRAS2 to DRAS0 in DRCRA, bits OIS3/2

and OS1/0 in 8TCSR3, bits CCLR1 and CCLR0 in 8TCR3, bit CS4E in CSCR, bit

NDER11 in NDERB, and bit PB3DDR select the pin function as follows.

Notes: 1. TMIO3 input when CCLR1 = CCLR0 = 1.

2. When an external request is specified as a DMAC activation source,

DREQ1 input regardless of bits OIS3 and OIS2, OS1 and OS0, CCLR1

and CCLR0, CS4E, NDER11, and PB3DDR.

CS4 is output as RAS4.
