2.2 Pin Names and Functions
Table 2.2 Shows the input/output pin names and functions.

(45 ~ 52)
Input/output or tristate
Lower address/data bus: Used as both the lower 8-bit address bus (output) and
data bus (bi-directional).
A8 ~ A15
Output
The upper 8-bit address bus.
P20 ~ P26
(A16 ~ A22)
7
(54 ~ 60)
Output
Port 2: A 7-bit output port. Outputs “0” after reset.
Address bus: The extension (upper) address bus. Outputs “0” after reset; there-
fore, the TMP90C051F address area is 0 - 64K bytes until a value other than
000H is written to EXPA0 and EXPA1 of the MMU register group after a reset;
therefore, A16 - A22 output zeros (0).
When a logical address indicates within the local area (local 0 or local 1) range
when the MMU is started, the physical addresses generated by the MMU are
outputs to A16 - A22.
Zeros (0) are output to A16 - A22 when a logical address indicates within the common
area (common 0 or common 1) range.
When an indirect extension address area is accessed using the CPU index regis-
ter the address value loaded to the BX or BY
When data are transferred using high-speed micro DMA, the address value loaded to
the DMA bank register is output to A16 - A22.
Output
register is output to A16 - A22.

Output
Read: The strobe signal output used to read data from external memory.
WR
Output
Write: The strobe signal output used to write data to external memory.
WAIT
Input
Wait: An input pin used to connect memory with slow access time and periph-
eral LSIs.
Non-maskable interrupt request pin:
The input pin used to generate interrupt requests on the fall edges
Port 30: A 1-bit output port. Outputs “1” after reset.
RAS: Outputs the RAS timing required for refreshing the DRAM of CAS before RAS.
Port 31: A 1-bit output port. Outputs “1” after reset.
CAS: Outputs the CAS timing required for refreshing the DRAM of CAS before RAS.
Port 32: A 1-bit output port. Outputs “1” after reset.
Chip select: The external memory chip select output pin. When a start address
and area size are loaded to the control register in the dynamic RAM controller,
“0” is output from the CS pin whenever the TMP90C051F accesses that address
range.
Port 33: A 1-bit output port. Outputs “1” after reset.
DMA active 0: Outputs zeros (0) while data are being transferred via high-speed
micro DMA channel 0.
