Name and Function
Row address strobe: DRAM row-address strobe-timing
signal.
Column address strobe high: DRAM column-address
strobe-timing signal outputs low level to access the
upper eight data bits.
Column address strobe low: DRAM column-address
strobe-timing signal outputs low level to access the
lower eight data bits.
Read: Indicates reading of data from an external device.
Upper write: Indicates write access to the upper eight
bits of an external device.
Lower write: Indicates write access to the lower eight
bits of an external device.
Chip select 0–7: Chip select signals for accessing
external memory and devices.
Address hold: Address hold timing signal for a device
using a multiplexed address/data bus.
Upper/lower byte strobe: Upper and lower byte strobe
signals. (Also used as WRH and A0.)
Write: Brought low during write access. (Also used as
WRL.)
DMA transfer request (channels 0 and 1): Input pins for
external DMA transfer requests.
DMA transfer acknowledge (channels 0 and 1):
Indicates that DMA transfer is acknowledged.
ITU input capture/output compare (channel 0): Input
capture or output compare pins.
ITU input capture/output compare (channel 1): Input
capture or output compare pins.
ITU input capture/output compare (channel 2): Input
capture or output compare pins.
ITU input capture/output compare (channel 3): Input
capture or output compare pins.
ITU input capture/output compare (channel 4): Input
capture or output compare pins.
