GENERAL-PURPOSE I/O (GPIO) PORTS

The PC87435 includes four types of General-Purpose I/O (GPIO) ports: Px, Py, Pz and Pw.



Px signals: Each signal is bidirectional and can be configured as input or output. An internal weak pull-up is provided to hold the pin high when used as an input or in an open-drain scheme.



Py signals: Each signal is input only. An internal weak pull-up is provided to hold the pin high.



Pz signals: Each signal is output only. It may be configured to work as totem-pole or in an open-drain scheme.



Pw signals: Each signal is bidirectional and can be configured for input or output. The Pw pins may be shared with development system functions. These ports can be implemented off-chip in

DEV environment using external logic.

GPIO Port Functionality

Ports IOPA(7-0), IOPB(7-0), IOPC(7-0), I OPD(7-0) and IOPF(7-0)

These ports are on-chip, General-Purpose Input/Output (GPIO) ports ( type Px).

IOPC0 is reserved for power supply control use. Bit 0 of PCALT, PCDIR, PCWPU and PCDOUT are reset on VCC Power-Up reset and WATCHDOG reset only.
PB6 is selected to its alternate function, by default (i.e., bit 6 is set to 1).
Ports IOPA4-0, IOPB2-0, IOPC0 and IOPD3 have the option to echo the value of the associated input.
Bit 5 of PBALT register, bit 0 of PCALT register and bits 4-7 of PDALT register are read only (RO) and return a value of zero.

IOPE(7-0) and IOPN(7-0)

These are General-Purpose Input (GPI) ports (type Py). IOPE(3-0) and IOPE5 do not implement the pull-up function, and the respective bits in PEWPU are reserved. IOPP has no alte rnate
function; thus it has no PyALT register.

IOPP(15-0)

This is a 16-bit General-Purpose Output (GPO) port (type Pz). Since IOPP has no alternate functions, its alternate function register is not implemented. The reset value of IOPP register is
FFFF16. IOPP has open-drain output drivers.

Ports IOPH(7-0), IOPI(7-0), IO PJ(7-0), IOPK(7-0) IOPL(4-0) and IOPM(7-0)

These ports are on-chip, General-Purpose Input/Output (GPIO) ports ( type Pw).

When the analog function is enable, the Read function, for GPIO signals that are multiplexed with analog functions, is disabled; this affects signals IOPN(7-0 ) and IOPE(3-0).
When the BIU function is enabled, the Read function, for GPIO signals that are multiplexed with BIU signals, is disabled; this affects signals PH(7-0), PI(7-0), PJ(1-0), PK(7-0), PL(7-0) and
PM(7-0).
