TWS Low-level Subroutines
Low-Level Subroutines
Functional Description
tws_setup(bus)
Initialize pointers to TWS registers. Must be
called prior to any TWS data transfers.
If Bus 0:
tws_data_ptr
= TWS_0_DATA (0xFD00)
tws_csr_ptr
= TWS_0_CSR (0xFD01)
If Bus 1:
tws_data_ptr
= TWS_1_DATA (0xFD02)
tws_csr_ptr
= TWS_1_CSR (0xFD03)
Return None.
tws_init
(bus speed, ID on bus)
Initialize the clock speed for specified bus
and ID.
Return None.
tws_poll_pin()
Return TRUE if Data Register completed
operation, FALSE if operation failed.
tws_poll_bb()
Return TRUE if bus free, FALSE if bus busy.
tws_poll_lrb()
Return TRUE if Last Received Bit (the ACK)
is logical 0 (successful) or FALSE otherwise
(failure).
tws_memory_write
(chip ID, address, number of
bytes to transfer, pointer to a
buffer)
Invoked only on a code load operation.
Parses the data to be written into small
groups (1–64 bytes) and repeatedly calls the
TWS write routine.
tws_write
(chip ID, address, number of
bytes to transfer, pointer to a
buffer)
With the pointers to the bus initialized, this
function writes the number of bytes from the
given buffer to the specified address and chip
ID.
tws_read
(chip ID, address, number of
bytes to transfer, pointer to a
buffer)
With the pointers to the bus initialized, this
function reads from the address and chip ID,
the specified number of bytes and stores the
data into the given buffer.
