H23

tsu(HAGPIO-COH)

Setup time, HAGPIO input mode before CLKOUT high(2)

H24

th(COH-HAGPIO)

Hold time, HAGPIO input mode after CLKOUT high(2)

H25

tsu(HDNMGPIO-COH)

Setup time, HDNMGPIO input mode before CLKOUT high(3)

H26

th(COH-HDNMGPIO)

Hold time, HDNMGPIO input mode after CLKOUT high(3)

H27

tsu(HDMGPIO-COH)

Setup time, HDMGPIO input mode before CLKOUT high(4)

H28

th(COH-HDMGPIO)

Hold time, HDMGPIO input mode after CLKOUT high(4)

H29

tsu(HCGPIO-COH)

Setup time, HCGPIO input mode before CLKOUT high(5)

H30

th(COH-HCGPIO)

Hold time, HCGPIO input mode after CLKOUT high(5)

(1)

In this case, CLKOUT reflects SYSCLK1. The CLKOUT Selection Register (CLKOUTSR) can be programmed to select SYSCLK1 as

CLKOUT.

(2)

HAGPIO refers to HPI.HA[15:0] configured as general-purpose input.

(3)

HDNMGPIO refers to HPI.HD[15:0] configured as general-purpose input during non-multiplexed operation of the HPI.

(4)

HDMGPIO refers to HPI.HD[7:0] configured as general-purpose input during multiplexed operation of the HPI.

(5)

HCGPIO refers to HPI.HAS (multiplexed mode only), HPI.HBIL (multiplexed mode only), HCNTL0, HCNTL1, HCS, HR/W, HDS1, HDS2,

HRDY, and HINT configured as general-purpose input.
